General Overview

The purpose of the JCapper WagerHistory Module is to give the player state of the art tools to:

 

1. Create and maintain a meaningful set of WagerHistory records.

 

2. Undertake an ongoing careful analysis of those records to recognize strengths and weaknesses.

 

3. Improve the bottom line going forward by taking corrective action to:

       

a. Scale back play in areas of recognized weakness.

 

        b. Ramp up play in areas of recognized strength.

 

 

Screenshots of Reports
The screenshots linked to below show the WagerHistory Module’s default report for some of my own (real not made up) wagering activity during 2012.

 

In the next few paragraphs I will discuss each of the screenshots, and hopefully, illustrate how and why proper record keeping can improve the player's bottom line going forward.

Short Description - All Wagers Are Not Created Equal
The first point I want to make is that all wagers are not created equal.

In the JCapper WagerHistory Module a concept is introduced called a SHORT DESCRIPTION. Simply put, a Short Description equates to THE REASON THE PLAYER HAS FOR MAKING THE BET IN THE FIRST PLACE.

The reason for making a bet varies from bet to bet and from player to player. In the JCapper WagerHistory Module, Short Description Codes are user defined. Short Description Codes must be created ahead of time in the Setup Screen. But once a Short Description Code has been created you can reuse it again and again each time you make a bet for the reason associated with that short description code.

 

The idea is to create unique Short Description Codes for each of the actual reasons you have for making a bet.

The first screenshot above shows wagering activity for bets that were tagged with a Short Description Code of HUNCH. As you might well guess, and this is backed up by the data on the report, hunch bets are best avoided by the serious player. Enough said.

 

The second screenshot above shows wagering activity for bets that were tagged with a Short Description Code of EXASVR. As you might well guess, EXASVR is a short description I use to describe an exacta saver bet. The negative results found in the report should come as no surprise to anyone. In fact they mimic long term results seen in the Data Window whenever I run my A and B UDMs through the JCapper Data Window and evaluate what happens if I play horses selected by A and B UDMs underneath other contenders in the exacta pool. Despite being fully aware of this phenomenon (for some dumb reason) I couldn’t help myself – and made (and recorded) these losing bets anyway.

The third screenshot above shows wagering activity for bets that were tagged with a Short Description Code of HIST while compiling the first half of the HIST wager history data sample. Note that all wagers appearing on the report totals shown in this screenshot were made BEFORE implementing the retooling effort discussed later on in this help doc.

 

The fourth screenshot above shows wagering activity for bets that were tagged with a Short Description Code of HIST while compiling the second part of the HIST wager history data sample. Note that all wagers appearing on the report totals shown in this screenshot were made AFTER implementing the retooling effort discussed later on in this help doc.

 

Note the differences in ROI on each of the reports. Also note that the last EXASVR bet was made was on 2/26/2012 and the last HUNCH bet was made was on 3/19/2012.

 

This speaks to the essence of the WagerHistory Module. All wagers are not created equal. Analyzing wagers using data points has value. Make no mistake. The reason you have for making a bet is a very important data point.

 

Careful analysis of data points enables the player to recognize strengths and weaknesses. Through the simple act of recognizing and avoiding known areas of weakness, as well as recognizing and ramping up play in known areas of strength, the player gains the ability to improve wagering performance going forward.

Again, the purpose of the JCapper WagerHistory Module is to give the player state of the art tools to:

 

1. Create and maintain a meaningful set of WagerHistory records.

 

2. Undertake an ongoing careful analysis of those records to recognize strengths and weaknesses.

 

3. Improve the bottom line going forward by taking corrective action to:

       

a. Scale back play in areas of recognized weakness.

 

        b. Ramp up play in areas of recognized strength.

 

 

 

 

 

 

Requirements/Getting the Module Up and Running

 

IMPORTANT - SQL Mode Required

The JCapper WagerHistory Module is designed to integrate (seamlessly) into JCapper under SQL Mode. Although parts of it do work when JCapper is operated in PlayList File Mode, this module is designed to be used when operating JCapper in SQL Mode.

 

IMPORTANT – Knowledge of SQL Required

Operating the WagerHistory Module effectively requires at least some knowledge of sql. A good benchmark is that if you can run the JCapper Data Window in sql mode then you can run the JCapper WagerHistory Report Generator with just a short learning curve.

 

Compatibility

The JCapper WagerHistory Module is compatible with all current versions of both JCapper Silver and JCapper Platinum.

 

Dummy Wager

The internal sql expressions that I am using in the module to enable the paging buttons to page through records in the WagerHistory table require that the WagerHistory table in the c:\JCapper\Exe\JCapper2.mdb file have at least one existing record - otherwise a BOF (Beginning Of File) error message will be generated when the WagerHistory module is first launched.

 

As of this writing, the WagerHistory table included with the latest JCapper program download package contains a $2.00 dummy wager tagged with a short description code of HUNCH. The purpose of the dummy wager is to prevent the interface from throwing a BOF (Beginning Of File) error message the first time you fire up the new module.

 

However, it is possible to unknowingly overwrite the dummy wager when you do a program install. Specifically, if you check the WagerHistory table box on the JCapper2 Imports Screen while importing JCapper2 table data from your old file into your new file – and if your old WagerHistory Table contains 0 records – you will cause the WagerHistory table dummy wager to be overwritten (deleted.)

 

Hint: If you get a BOF error message the first time you fire up the WagerHistory Module – try not to panic. There’s a 99 percent chance that the error message means there are 0 records in the WagerHistory table and that you just need to create record number 1 in the WagerHistory table manually.

 

 

Instructions for Auto-generating a “dummy” WagerHistory table record:

Upon startup, the Data Entry Sheet tests the WagerHistory table and counts the number of table records. If at least 1 table record is found the module loads (and runs) normally.

 

If 0 table records are found, instead of a BOF message, and instead of the user having to manually enter a "dummy wager" as the 1st table record - here's what happens:

 

1. The user is notified that 0 table records exist and is then prompted: "Do you wish to Create a 'dummy wager' as the 1st table record Y/N?"

 

2. Upon answering Y at the prompt, the interface auto generates table record number 1 with a made up track code, race number, and horse name - and the module loads normally from there.

 

Hint: After using the WagerHistory Module to record at least one real wager, consider deleting the “dummy” wager.

 

Although it is probably easier to auto generate a “dummy wager” to initialize the module, alternately, the first table record can be created manually.

 

 

Instructions for manually creating a "dummy" WagerHistory table record:

 

  1. Follow the procedure outlined in the Setup Screen section (below) to create at least one Short Description Code.

 

  1. Run a sql calc races. This will populate the tables with needed data about horses from today's races.

 

  1. Launch the Data Entry Screen. Ignore the BOF error message when it comes up. (Just click ok at the message box.)

 

  1. Click the NEW button on the Data Entry Screen. This will engage the Create New Record Sequence.

 

  1. Fill in some data points for your dummy record:

 

    1. Key in a track code and race number.

 

    1. Select a horse name from the horse names drop down.

 

    1. Select a Short Description from the Short Description Code Drop Down.

 

    1. Select a wager type from the wager type drop down (win works for this purpose.)

 

    1. Manually key 2.00 as the Amount Wagered.

 

  1. Hit the save button.

 

Congrats. You now have a dummy wager as record number 1 sitting in the WagerHistory table.

 

From here, exit the Data Entry Sheet and run a SQL Mode Calc Races routine.

 

The next time you launch the Data Entry Sheet you should find that the BOF error is a thing of the past and that you can now operate the WagerHistory Module exactly as described in this Help Doc.

 

Hint: After using the WagerHistory Module to record at least one real wager, consider deleting the “dummy” wager.

 

 

 

 

 


JCapper WagerHistory User Interface

To launch the WagerHistory Module, click the WgrHist button on the face of the JCapper Main Module. When the WagerHistory Module is first launched, the very first screen that comes up is the WagerHistory User Interface.

 

WagerHistory User Interface screenshot:

http://www.JCapper.com/Messageboard/Avatars/WagerHistUserInterface.jpg

 

The WagerHistory User Interface has a simple design. You the user are presented with buttons, that when clicked, will enable you to navigate to the individual screens that collectively make up the WagerHistory Module. (To get into any area of the WagerHistory Module, simply click the launch button for that area.)

 

 

 

 

 

 

JCapper WagerHistory Setup Screen

The purpose of the JCapper WagerHistory Setup Screen is to enable you to create Short Description Codes.

 

Short Description Field

In JCapper, a Short Description is a user defined string of up to 18 text characters used to describe the reason the player has (or had) for making an individual bet. The player has the ability to set up unique short description codes ahead of time - one short description code for each reason for making a bet. Then during record keeping, when actual tickets are written to the table, the player can tag each bet made with the appropriate short description code.

 

Tagging individual tickets with a Short Description Code enables you to generate wager history reports that will evaluate your own performance in terms of why each bet was made.

 

Bets made for like reasons can be reported on separately. Once sufficient wager history has been amassed, strong reasons for making a bet are readily identified (as are weak reasons.) From there, corrective action can be taken as needed.

 

JCapper WagerHistory Setup Screen screenshot:

http://www.JCapper.com/Messageboard/Avatars/WagerHistSetup.jpg

 

The above screenshot shows the Setup Screen after creating a Short Description Code. Note that I used the characters VSFAV in the Short Description field and the characters Taking a Stand vs Overbet Favorite in the Long Description field. As you might well have been able to guess, VSFAV is a Short Description Code that can be used to tag wagers made where the primary reason for making the bet is a belief that the post time favorite is:

1. Vulnerable.

2. Overbet.

 

Your goal when setting up your own Short Description Codes: Create one short description code for each reason you have for making a bet.

 

 

Long Description Field

The Long Description field is used to hold a longer text description describing the reason you have for making a bet. A long description can be any combination of keyboard characters you want – up to 72 characters in length.

 

Creating a New Short Description Code

Here are the steps to create a new Short Description Code:

 

  1. Click the NEW Button

 

  1. Key your Short Description (up to 18 characters in length) into the Short Description field.

 

  1. Key your Long Description (descriptive text up to 72 characters in length) into the Long Description field.

 

  1. Click the SAVE button.

 

Hint: The shorter your Short Description Codes the better. Most of mine are just 4-6 characters in length. (This makes for reports that are easy to read because they are not cluttered up.)

 

 

Editing an Existing Short Description Code

Here are the steps to edit an existing Short Description Code:

 

  1. Select an existing Short Description Code from the drop down.

 

  1. Edit the Short Description field as needed.

 

  1. Edit the Long Description field as needed.

 

  1. Click the SAVE button.

 

  1. Or, alternately, abandon the edit process by not clicking the Save button. For example, instead of clicking the Save button, x-out of the Setup Screen to avoid editing the selected Short Description Code.

 

 

Deleting an Existing Short Description Code

To delete an existing Short Description Code:

 

  1. Select the existing Short Description Code that you want to delete from the drop down.

 

  1. Click the Delete button and answer Yes when prompted by the interface to confirm that you do in fact want to delete the current Short Description Code.

 

  1. Or, alternately, abandon the delete process by not clicking the Delete button. For example, instead of clicking the Delete button, x-out of the Setup Screen to avoid editing and/or deleting the selected Short Description Code.

 

 

Note: The first few times that you are in the WagerHistory Module you will need to bring up the Setup Screen to create Short Description Codes – one Short Description Code for each reason you have for making a bet. After creating a handful of Short Description Codes you will yourself in the Setup Screen less frequently. After a while, you will seldom find yourself in the Setup Screen – as the only time you need to go into to the Setup Screen is when you’ve identified a new reason for making a bet and you need to create a new Short Description for that reason.

 

 

 

 

  

 

JCapper WagerHistory Data Entry Sheet

The Data Entry Sheet is designed to enable you to record detailed info about each wager that you make. Info recorded can include info about individual playing sessions, size of bankroll, info driving your bet sizing, the reason why you made the bet in the first place, various attributes about the bet not found elsewhere in JCapper, and an electronic copy the ticket for each of your wagers.

 

Screenshot - JCapper WagerHistory Data Entry Sheet:

http://www.jcapper.com/messageboard/avatars/WagerHistDataEntry01.jpg

 

The Data Entry Sheet interface is broken up into three sections: The Bankroll Summary Section, the UDM/Races Section, and the Wager Detail Section. Each section is presented individually below.

 

IMPORTANT - SQL Mode Required

The JCapper WagerHistory Interface is designed to integrate (seamlessly) into JCapper under SQL Mode. Although parts of it do work when JCapper is operated in PlayList File Mode, this module is designed to be used when operating JCapper in SQL Mode.

 

JCapper2.ldb Lock File

When the WagerHistory Module Data Entry Sheet is launched it places a lock condition on the c:\JCapper\Exe\JCapper2.mdb file so that it can read and write to the WagerHistory table. After launching the Data Entry Sheet, if you navigate to the c:\JCapper\Exe folder and look at the names of files on that folder, you will see the following lock file: c:\JCapper\Exe\JCapper2.ldb. As soon as the Data Entry Sheet is terminated the lock condition is removed, and the c:\JCapper\Exe\JCapper2.ldb lock file is automatically deleted by Windows.

 

I mention this because while the lock condition remains in effect – you will not be able to run a Calc Races routine. If you try to run a Calc Races routine and receive a message box telling you: The c:\JCapper\Exe\JCapper.mdb file is currently locked by another application – the very first thing you should suspect is that the JCapper2.mdb file has been locked by the Data Entry Sheet – and that this can be corrected simply by X-ing out of (closing down) the Data Entry Sheet.

 

Alternately, the lock condition can be removed (the lock file deleted and the JCapper2.mdb file freed up) by clicking the Disconnect Button. FYI, the Disconnect and Reconnect buttons are discussed in the UDM Races section later on in this help doc.

 

 

 

 

Bankroll Summary Section

This section is designed to facilitate tracking of ADW account balance (or simply cash on hand if you are not using an ADW) and to facilitate bet sizing relative to both strength of play and size of current bank. A short description about each of the bankroll summary data fields and buttons is listed below.

 

SessionID Field

Use this data field to assign a unique ID character string (or name) for each playing session. By referring to the SessionID field as part of SQL expressions that you create for WagerHistory reporting, you will be able to generate reports that display all wagers for specific playing session(s.) Note that the interface is designed in such a way that you would record a value in this field (once) at the start of each playing session only. (There is no reason to change the value of this field during a playing session.) You would, however, enter a new value in this field at the start of each new playing session.

 

Account Balance Start Point

Use this data field to record the ADW account balance (or simply cash on hand if you are not using an ADW) at the start of each playing session. The interface will use the info in this data field as part of its bankroll/bet sizing calculation going forward. Note that the interface is designed in such a way that you would record a value in this field (once) at the start of each playing session only. (There is no reason to change the value of this field during a playing session.) You would, however, enter a new value in this field at the start of each new playing session.

 

Current Account Balance

Use this data field to record the ADW account balance (or simply cash on hand if you are not using an ADW) just prior to making each wager. The interface will use the info in this data field as part of its bankroll/bet sizing calculation going forward. Note that the interface is designed in such a way that you would record a new value in this field for each new wager persisted to the WagerHistory table. Keying a new value into this data field just prior to recording a new wager allows you to size each (new) wager relative to (new) current bankroll size. Optionally, this data field can be updated periodically (whenever you decide it best to recognize new current bankroll size.)

 

Starting Session Bankroll

Use this data field to record the amount of the starting bankroll for each playing session. Note that the interface is designed in such a way that you would record a value in this field (once) at the start of each playing session only. (There is no reason to change the value of this field during a playing session.) You would, however, enter a new value in this field at the start of each new playing session.

 

Current Session Bet Pct

Use this field to record the percentage of bankroll for each wager persisted to the WagerHistory table. Note that the interface is designed to provide several methods for getting data into this field. You can key a value into this field manually. Clicking one of the bankroll sizing buttons located immediately beneath this data field will cause it to be auto populated. Additionally, clicking the Kelly button located on the upper right side of the interface will cause this data field to be auto populated.

 

Current Session Bankroll

The interface is designed in such a way that you would not (normally) enter data into this field. Instead, it is auto populated as part of the bankroll/bet sizing calculation using available info obtained from other data fields.

 

Calculated Bet Size

The interface is designed in such a way that you would not (normally) enter data into this field. Instead, it is auto populated as part of the bankroll/bet sizing calculation using available info obtained from other data fields.

 

Bet Sizing Buttons

Several buttons are provided for Pct of Bankroll Bet Sizing. Each button is labeled with a numeric percentage of bankroll. Clicking a button causes the interface to perform its bankroll/bet sizing calculation (using the percentage of bankroll appearing on the face of the button) and populate appropriate data fields on the interface with the results of the calculation.

 

Bolded Bet Sizing Button

Note that one of the bet sizing buttons is bolded. The percentage of bankroll value displayed on this button is the same as the value persisted by the user on the User Sys Defs Screen. (This means you can control the percentage of bankroll appearing on this button and used by the interface in its bankroll/bet sizing calculation by editing the bankroll settings found on the User Sys Defs Screen.) Clicking this button causes the interface to perform its bankroll/bet sizing calculation (using the percentage of bankroll appearing on the face of the button) and populate appropriate data fields on the interface with the results of the calculation.

 

Calculate Button

Click this button to make the interface perform its bankroll/bet sizing calculation after manually keying a percentage of bankroll value into the Current Session Bet Pct data field. (You would not otherwise have reason to click this button.)

 

 

 

 

 

 

The UDM/Races Section

This section of the interface enables you to quickly spot races that have UDM selections. The visual elements in this section of the interface are presented below.

 

UDM Races Listbox

The UDM Races Listbox, when populated, displays a list of races that have UDM selections. The rules for making UDM selections appear in the UDM Races Listbox are the same as those governing whether or not horses selected by UDMs appear on both standard JCapper Text Report and inside the SQL Mode UDM Reports Module. To make horses selected by a UDM appear in these three areas of the JCapper program, on the Modify Screen of the UDM Wizard: 1. Uncheck the Hide From Text Report Checkbox. 2. Use Mark Characters associated with positive expectation UDMs (avoid Mark Characters associated with Negative Expectation UDMs.) If the selections of a UDM appear on a JCapper Text Report, they will also appear in the SQL Mode UDM Reports Module and in the WagerHistory Data Entry Screen UDM Races Listbox.

 

Note that individual rows displayed in the UDM Races Listbox are clickable. To initiate a WagerHistory table entry for a horse displayed in the UDM Races Listbox: double click that row.

 

Populate Button

Click the Populate Button to populate the UDM Races Listbox with a list of UDM plays for card files loaded into the program.

 

Prerequisite for populating the UDM Races Listbox:

Before you can populate the UDM Races Listbox you must first run a Calc Races in SQL Mode. Failure to do this will result in inability to populate the Listbox.

 

Find Button

Clicking the Find button will cause the interface to pull up wager detail for the row currently selected in the UDM Races Listbox. To populate the Wager Detail Section of the interface for a horse displayed in the UDM Races Listbox: Single click the row for that horse and click the Find button. (Optionally, you can double click the row for that horse without clicking the Find button.)

 

UDMs Button

Clicking the UDMs button causes the UDM Profile Window in the Wager Detail section of the interface to switch display types. If the UDM Profile is currently displayed when the UDMs button is clicked a text report showing wager detail will be displayed. If the text report showing wager detail is displayed when the UDMs button is clicked the display mode is switched and the UDM Profile is displayed. Note that the UDMs button in the UDM/Races Section of the interface and the Detail button in the Wager Detail Section of the interface both perform the same function.

 

The Deselect Button

Clicking the Deselect button causes any selected item (or currently highlighted row) in the UDM Races Listbox to become deselected (or un-highlighted.) You would normally click this button just prior to clicking the New button in the Wager Detail Section of the interface when you want to create a new table entry for a horse other than the one currently selected/highlighted in the UDM Races Listbox.

 

Disconnect Button

Clicking the Disconnect Button causes the WagerHistory Data Entry Sheet interface to close its database connection with the c:\JCapper\Exe\JCapper2.mdb file. You would normally click this button to remove the lock file placed on the c:\JCapper\Exe\JCapper2.mdb file by the WagerHistory Data Entry Sheet – For example: You would click the Disconnect button to unlock/free up the JCapper2.mdb file so that you can run a SQL Calc Races using the JCapper Main Module. Alternately, the lock file can be removed (the JCapper2.mdb file freed up) by X-ing out of (closing down) the WagerHistory Data Entry Sheet.

 

Reconnect Button

Clicking the Reconnect Button causes the WagerHistory Data Entry Sheet interface to reconnect to the c:\JCapper\Exe\JCapper2.mdb database file. You would normally click the Reconnect button under the following circumstances: 1. You previously clicked the Disconnect button to unlock the c:\JCapper\Exe\JCapper2.mdb database file. 2. You are finished running a non WagerHistory routine such as a Data Window query or SQL Calc Races involving the  c:\JCapper\Exe\JCapper2.mdb database file. 3. You are ready to once again use the WagerHistory Data Entry Sheet. Alternately, you can reestablish a database connection by closing down and relaunching the WagerHistory Data Entry Sheet interface.

 

 

 

 

 

 

The Wager Detail Section

This section of the interface is designed to enable you to record various details about each wager that you make. Not all of the data fields in this section of the interface are required data fields. (Many are optional.) However, it goes without saying that the more detail recorded about your wagers, the greater the depth your wager history analysis can take on.

 

Data Fields Section

A short description of each of the wager detail data fields is listed below.

 

Strike Price

Use this (optional) field to record the strike price (min required odds) you need in order to bet a horse profitably. Initially, your strike price might be subjective – something as simple as entering the odds line number (or some multiple of the odds line number) displayed on the html report for the horse you are about to bet.

 

Odds 1 MTP

Use this (optional) data field to record the odds close to post time (or decision odds) just before making play or pass decisions about horse(s) you are about to bet.

 

Estimated Edge

This (optional) data field has been provided to enable you to record an estimated edge for each bet that you make. The value recorded in the estimated edge field might (initially in your first sample) be your own best attempt at estimated edge.

 

Better yet, the value recorded in this field might also be something that you calculate mechanically. For example, it could be a value resulting from an algorithm of your own creation where you are attempting to tag each recorded bet with a numeric value that (at first and loosely) represents strength of play – but is also something that improves with time as future analysis and review of its strengths and weaknesses is undertaken.

 

Estimated Edge Auto Calc function

An Estimated Edge Auto Calc function is built into the interface.

 

To use the auto calc function: First populate data fields for strike price, decision odds, physicality, track weight, and UDM counters. Then double click the estimated edge field and answer Y when prompted. The interface contains an algorithm that will evaluate all available information about the current horse (including field size) before auto populating the estimated edge field. The advantage to using the auto calc function is that estimated edge is calculated in the same manner every single time.

 

Once you have compiled strike price, decision odds, and estimated edge data about the horses you bet, you will be able to use the WagerHistory Report Generator to run reports showing your actual wager history broken out by different facets related to play or pass decision making. This will (hopefully) enable you to improve your play or pass decision making going forward.

 

Consistency within a Sample

One advantage of using the estimated edge auto calc function is that values recorded in the estimated edge field are calculated in an identical manner every single time.

 

Why is this important?

 

Wager history data itself can be rendered useless when recorded data points are arrived at in a haphazard manner. (This is true for any type of data.)

 

If you do decide to roll your own when arriving at values recorded in the estimated edge field: Whatever methodology you use, insist that calculated values going into the estimated edge field be generated in a nearly identical manner for all wagers recorded within an individual sample.

 

 

 

Kelly Button

Much has been written about using the Kelly Criterion as a method to determine bet sizing. The theory behind it goes something like this:

 

Optimal Bet Size  = (Estimated Edge) divided by (Odds)

 

Suppose Estimated Edge (ROI to $1.00) is 1.12. Put anther way: percentage advantage is 12 percent. Further, suppose that the odds at decision time are 3-1. Using Kelly, optimal bet size is calculated as follows:

 

Optimal Bet Size  = (Estimated Edge) / (Odds)

 

Optimal Bet Size = (.12) / (3)

 

Optimal Bet Size = .04

 

Or

 

Optimal Bet Size = 4 percent of bankroll.

 

Experience has taught me the following:

Using Kelly to determine wager size works really well if and only if the player is able to estimate the edge accurately. Using Kelly to determine bet size will have disastrous consequences for the player in the event the player errs when estimating his or her edge.

 

Nonetheless, for players who believe they have gained the ability to estimate their edge with reasonable accuracy (through record keeping and analysis of their own wager history) I have included the Kelly button as part of the Data Entry Sheet interface.

 

Clicking the Kelly button causes the interface to read the values from the Estimated Edge and Odds 1 at MTP fields, make a Kelly bet sizing calculation by plugging estimated edge and decision odds into the above formula – with the resulting bet size output to the the Calculated Bet Size and Bankroll Pct data fields located on the left hand side of the interface.

 

IMPORTANT: If you are the least bit unsure about your ability to accurately estimate your edge, avoid using the Kelly button for bet sizing. Instead of the Kelly button, consider using one of the Pct of Bankroll buttons on the left side of the interface.

 

Bet sizing is an extremely important part of growing a bankroll. Before making any decisions about the bet sizing part of your game, consider doing some extensive Data Window R&D first – with the objective in mind of becoming somewhat educated about what bet sizing might be appropriate for each of your UDMs. Believe me when I say this. This is an extremely important area (one that most players give very little thought to.)

 

Experiment a little. Use the Enhanced Settings Module to persist various bet size percentages. Then immediately run each of your active UDMs through the Data Window using the new bankroll setting and make a careful analysis of the Bankroll Summary Section displayed towards the bottom of your Data Window results. Save the Data Window results (in a text file) for future reference and then repeat using different bankroll settings.

 

Each of your UDMs will likely have a different strength of play. It is therefore likely that each of your UDMs will require slightly different bet sizing. If you are the least bit unsure about how to size your bets, accept the fact that until you get considerable experience under your belt you are going to err when it comes to accurately sizing your bets. Go with the following philosophy: If you must err, then err on the side of caution. Make smaller bets rather than larger – at least until you have sufficient wager history (and experience) behind you.

 

 

Physicality

This (optional) numeric data field has been provided to enable the player to record a score for horse physicality. This field is optional as compiling data based on your interpretation of horse physicality may (or may not) be something you are interested in. If horse physicality is not your thing, feel free to use this field to record a number that represents something else.

 

Estimated Track Weight

This (optional) numeric data field has been provided to enable the player to record a score for Estimated Track Weight. This field is optional as compiling data based on your interpretation of estimated track weight may (or may not) be something you are interested in. If track weight is not your thing, feel free to use this field to record a number representing something else.

 

UDM Count Data Fields

A well thought out set of UDMs can paint a very accurate picture about the strengths and weaknesses of horses flagged by them. The interface enables the player to persist a hard count of each UDM type to the WagerHistory table. Once enough data has been recorded, the interface enables the player to gain valuable insight about the way his or her UDMs interact with one another for the horses bet by the player.

 

The interface was designed around the following UDM types:

 

A UDMs – These are your best business UDMs – the ones you (should) put most of your focus on.

 

B UDMs – These are good UDMs (that under the right conditions) can point out playable horses. But they are not as good as your A UDMs.

 

Negative Expectation UDMs – These are UDMs designed to point out weaknesses in horses flagged by them.

 

UDM Count – A

Use this (optional) data field to record the number of A UDMs flagging an individual horse.

 

UDM Count – B

Use this (optional) data field to record the number of B UDMs flagging an individual horse.

 

UDM Count – Neg

Use this (optional) data field to record the number of Negative Expectation UDMs flagging an individual horse.

 

UDM Count Auto Populate Feature:

When a new record is created for a horse, the interface assembles and displays the UDM profile for that horse. To relieve the player of the (tedious) need to manually determine (and key in) the count of UDMs by UDM type for each horse, the interface contains an algorithm that robotically counts the number of UDMs (by UDM type) found in a horse’s UDM profile. When the UDM profile is first pulled up by the interface, the player is prompted by the interface (Y or N) whether or not to auto populate the UDM count data fields. Answering Yes when prompted will cause the interface to auto populate the UDM count data fields.

 

UDM Naming Schema:

The following UDM Naming Schema will enable the Auto Populate Function to identify UDMs according to UDM type:

 

A UDMs – First 4 characters: 0_A-

B UDMs – First 4 characters: 0_B-

Neg UDMs – First 2 characters: X_

Neg UDMs – First 2 characters: Z_

Neg UDMs – First 3 characters: XX_

Neg UDMs – First 3 characters: ZZ_

 

If the auto populate function does not appear to be working for you: Double check your UDM names against the above naming schema. Use the Modify UDM Screen in the UDM Wizard to edit your UDM names accordingly.

 

Date Field

This (required) field is provided to record the date.

 

When the Data Entry Sheet is first launched, the last entry in the WagerHistory table is auto displayed. When you click the NEW button to begin data entry for a new wager, the date field will (initially) be populated with the date of the last entry in the table.

 

Clicking the date field will launch a calendar control. With the calendar control launched, select the race date for the new wager you are about to entry and hit the Apply button. The calendar control will paste the selected date into the Date field. From there, move to the next field.

 

Track Field

This (required) field is provided to record the 3 character track code for each wager.

 

Manual data entry of track code:

Key the 3 character track code for the new wager you are about to enter into the Track field. Note that in JCapper, track codes are 3 characters in length. Also note that the track code is the same as the first 3 characters of the file name of the past performance data file for each track. After manually keying a track code into the Track field, navigate to the Race Drop Down using the Tab key. As soon as you navigate to the Race field, the Race Drop Down will auto populate with a list of races for the track and date you are working with.

 

Race Drop Down

This (required) field is provided to record the race number for each wager.

 

Manual data entry of race number:

Select a race number and navigate to the Horse Name Drop Down using the Tab key. As soon as you navigate to the Horse Name Drop Down (provided that you have provided the interface with valid info for date, track, and race number) the Horse Name Drop Down will auto populate with a list of horses for the current race.

 

Horse Name Drop Down

This (required)  field is provided to record the horse name for each wager. Note that the very last horse listed in the drop down is not a horse name at all. When entering wagers that are multi horse based rather than single horse based: select MULTI HORSE WAGER from the drop down. When entering wagers that are primarily based on a single horse: select the appropriate horse name from the drop down.

 

UDM Profile Window

After selecting a single horse from the Horse Name drop down, the interface will pull up the horse’s UDM Profile using info from tables found in the c:\ JCapper\Exe\JCapper2.mdb file. The interface will also display the horse’s UDM Profile in the UDM Profile Window. Note that the UDM Profile is the same as that displayed on the SQL Mode HTML Report and the SQL UDM Plays Reports Module.

 

Note: As mentioned above in the section covering the UDM Count data field, once the UDM Profile is first created, you will be asked Y/N to see if you want the interface to auto populate the UDM Count data fields.

 

Short Description Drop Down

This (required) drop down field is provided to record the Short Description (or reason) for making the bet.

 

Within the context of the JCapper WagerHistory Module, a Short Description is a user defined code (created in the Setup Screen) that relates to the reason for making a bet.

 

IMPORTANT NOTE: Before using the Data Entry Sheet to record your wagers, you should first use the Setup Screen to create one Short Description for each reason you can think of for making a bet. Then, when using the Data Entry Sheet to create table entries describing your wagering activity, select the one Short Description from the drop down that best describes the reason why you made the current bet that you are recording.

 

UDM Name Drop Down

This (optional) drop down data field is provided to record the name of the primary UDM flagging the horse.

 

UDM Name Auto Selection Routine

When multiple UDMs are flagging the current horse, an algorithm will auto select the UDM that (initially) appears in the UDM Drop Name Down. The programming behind the algorithm is simple: First, only active UDMs are eligible for auto selection. Next, only UDMs having the Hide From Text Report box unchecked in the UDM Wizard Modify UDM Screen are eligible for auto selection. Lastly, Negative Expectation UDMs are not eligible for auto selection.

 

Note that these rules are the same as those used by the Profile Marker to determine whether or not UDMs appear on the Text Report. The auto selection rules can be restated as follows: UDMs that are eligible for auto selection are simply those that appear on the Text Report.

 

Once the list of eligible UDMs has been determined, the list is sorted, and the eligible UDM on the list named in such a way that it would be displayed first (on top) in the SQL Mode Text Report (or alternately in the SQL Mode UDM Plays Report) is the UDM auto selected by the interface to appear in the UDM Name Drop Down.

 

To override the auto selected UDM: select a different UDM from the UDM Name Drop Down.

 

Paging Buttons

Beneath the UDM Profile Window are several paging buttons designed to enable you to page through the entries you have made to the WagerHistory table (your wager history.)

 

FIRST Button

Clicking this button causes the interface to pull up and display detail for the very first record in the WagerHistory table.

 

BACK Button

Clicking this button causes the interface to go back one record in the table, pull up that record, and display detail for it. Note that if the BACK button is clicked when the very first record in the table is displayed a message is generated alerting you to this fact. (You are already looking at detail for the first record in the table.)

 

NEXT Button

Clicking this button causes the interface move forward one record in the table, pull up that record, and display detail for it. Note that if the NEXT button is clicked when the very last record in the table is displayed a message is generated alerting you to this fact. (You are already looking at detail for the last record in the table.)

 

LAST Button

Clicking this button causes the interface to pull up and display detail for the very last record in the WagerHistory table.

 

EDIT Button

Clicking this button enables you to edit detail for the current record (the record currently displayed by the interface.) The interface will alert you to this fact by displaying the following message: Edit Record Sequence Engaged. Note that the interface also displays the phrase Edit Record Sequence Engaged on the title bar going across the very top of the Data Entry Screen. This provides you a visual cue that the Edit Record Sequence has in fact been engaged. While the Edit Record Sequence is engaged the SAVE button is enabled.

 

To edit detail for the current record:

  1. Key your changes into the desired data field.
  2. Save your work by clicking the SAVE button.

 

Alternately, you can abandon the Edit Record Sequence and avoid saving changes by paging to a different record without clicking the Save button. For example, changes to the current record can be abandoned (not persisted to the table) by clicking the Back button instead of the Save button.

 

 

Creating a New Record for UDM horses displayed in the UDM Races Listbox

To create a new record for a UDM horse displayed in the UDM Races Listbox, do not (repeat not) click the New button.

 

Instead of clicking the New button:

 

After running a SQL Mode Calc Races, click the Populate Button to populate the UDM Races Listbox with a list of UDM plays for card files loaded into the program.

 

Double click the horse name in the UDM Races Listbox that you want to create a new record for.

 

This will cause the interface to begin creating a new record for that specific horse. The interface will alert you to this fact by displaying the following message: Create New Record Sequence Engaged. The interface will also provide you a visual cue that the Create New Record Sequence has been engaged by displaying the phrase Create New Record Sequence Engaged on the title bar going across the very top of the Data Entry Screen.

 

Immediately upon clicking OK in response to the Create New Record Sequence Engaged message, the interface will present you with the following prompt: Auto Populate UDM Counters to UDM Profile Y/N?

 

Clicking Y at this prompt will cause the interface to pull up the UDM profile for the selected horse and auto populate the UDM Count Data Fields using the UDM naming schema for A, B, and Negative UDMs as described in the UDM Count Data Fields section presented above in this help doc.

 

Clicking N at this prompt will cause the interface to not auto populate the UDM Count Data Fields for the selected horse.

 

From here, use the interface to key info for the remaining data fields and save your work by clicking the SAVE button.

 

Alternately, you can abandon the Create New Record Sequence and avoid creating a new record by paging to a different record without clicking the Save button. For example, creating a new record can be abandoned (not persisted to the table) by clicking the Back button instead of the Save button.

 

 

 

 

Creating a New Record for horses NOT displayed in the UDM Races Listbox

 

NEW Button

Clicking the New button will enable you to create a new record for a horse (or horses) not displayed in the UDM Races Listbox.

 

After the New button is clicked, the interface will tell you that you are creating a new record by displaying the following message: Create New Record Sequence Engaged. The interface will also provide you a visual cue that the Create New Record Sequence has been engaged by displaying the phrase Create New Record Sequence Engaged on the title bar going across the very top of the Data Entry Screen.

 

Manual Procedure for Creating a New Record:

 

  1. Immediately after clicking OK in response to the prompt Create New Record Sequence Engaged, the cursor will be inserted into the Track field on the Wager Detail Section of the interface. Once you see the cursor blinking in the Track field: Key your 3 character track code into the Track field and hit the TAB key to navigate to the Race field.

 

  1. Key the race number into the Race field. Or alternately, select a race number from the Races drop down. After supplying a race number, the interface will auto populate the horses drop down with names of horses for that race.

 

  1. Select a horse name from the horse name drop down. Or alternately, if your wager more closely relates to multiple horses than a single horse, select MULTI HORSE WAGER from the horse name drop down. After supplying a horse name (or selecting the alternate Multi Horse Wager option) the interface will present you with the following prompt: Auto Populate UDM Counters to UDM Profile Y/N?

 

Clicking Y at this prompt will cause the interface to pull up the UDM profile (if any exists) for the horse name provided  and auto populate the UDM Count Data Fields using the UDM naming schema for A, B, and Negative UDMs as described in the UDM Count Data Fields section presented above in this help doc.

 

Clicking N at this prompt will cause the interface to not auto populate the UDM Count Data Fields for the horse name provided.

 

Note: When the Multi Horse Wager option has been selected from the horse name drop down, there is no UDM profile to be pulled up

.

  1. Key in information for those data points you wish to capture about the wager. Use the data fields provided in the Wager Detail Section of the interface.

 

  1. Save your work by clicking the Save button. Alternately, abandon the Create New Record Sequence and avoid creating a new record by paging to a different record without clicking the Save button. For example, creating a new record can be abandoned (not persisted to the table) by clicking the Back button instead of the Save button.

 

 

Best Practices

 

Consistency

The wager history that you create using this module will have value to you for purposes of future analysis only if the data points captured for each wager are created in a consistent manner.

 

Take for example the Short Description field. The screenshots at the very top of this help doc serve to illustrate differences in player expectation going forward based on the reason for making the bet.

 

In the case of the HIST data sample, EVERY single wager recorded was assigned its short description code for a very specific reason.

 

First, the horse itself had to be selected by one or more of my A UDMs. Further, every single one of those A UDM horses that I wagered on went to post under a nearly identical predefined set of standards.

 

Because assignment of the HIST short description code was made in a nearly identical manner for every single recorded wager, and made to a predefined set of standards, the wager history data itself turned out to be useful as well as interesting. This became apparent to me once I had amassed enough data and began analyzing it. I very strongly believe that the usefulness of the wager history data itself would have been weakened considerably had assignment of the short description code been made in a more haphazard manner.

 

The same can be said for all of the other data points found on the interface. Consistency matters.

 

 

 

 

 

 

Ticket Calculator

The purpose of the Ticket Calculator is to enable you to create an electronic copy (or ticket) of every wager that you make.

Creating a Ticket.
Screenshot - Ticket Calculator
On the Data Entry Sheet, fill out everything about the horse you want to record a wager for (Short Description, Date, Track, Race, Horse, etc.) and click the Ticket Calculator button.

 

If the create new record sequence is not already engaged when you click the Ticket Calculator button, the interface will ask you (Y or N) whether or not you want to Clone the current record. Answer Y at the prompt to create a new ticket for the horse. Answer N at the prompt if you simply wish to edit the ticket detail for the current record. After answering Y or N at the prompt, the interface will launch the Ticket Calculator.

 

The steps for using the Ticket Calculator to create a ticket are as follows:

 

1. Click one or more of the Wager Amount Buttons to key in base wager amount. The above linked to screenshot shows a $40 win wager. For that screenshot I hit the 4 button followed by the 0 button to make the interface arrive at a wager amount of $40.

 

2. Click the Wager Type Button that corresponds to the type of wager (pool) for the bet you are making. The above linked to screenshot shows a $40 win wager. For that screenshot after hitting the 4 button and the 0 button to make the interface arrive at the $40 wager amount: I hit the WIN button to tell the interface I was making a win bet. Note that clicking any of the wager type buttons causes the appropriate horse number drop down(s) to appear for that wager type (which leads into the next step below.)

 

3. Click the individual horse number(s) on the horse number drop down(s) to indicate individual horse numbers for your ticket. The above linked to screenshot shows a $40 win wager on the number 7 horse. For that screenshot, after indicating wager type in step 2 above, the interface displayed the Leg A horse drop down and I selected the 7 horse by clicking horse number 7 on the drop down.

 

Note that had I been making an exacta bet (and had I clicked the EXA button) the interface would have displayed both the Leg A and Leg B horse number drop downs. Had I been making a trifecta bet (and had I clicked the TRI button) the interface would have displayed the Leg A, Leg B, and Leg C drop downs. Had I been making a superfecta bet (and had I clicked the SUPER button) the interface would have displayed the horse number drop downs for Leg A, Leg B, Leg C, and Leg D.

 

4. Verify ticket detail. Hint: Ticket detail is always displayed in the Ticket Detail Window.

 

5. Click the Write Ticket to Data Entry Sheet Button to persist ticket detail back to the Data Entry Sheet.

 

 

 


Step 2. Work up Amt Collected.
Screenshot - Amt Collected Tool
Click the Amt Collected field on the Data Entry Sheet and you will be prompted to launch the Amt Collected Tool. The Amt Collected Tool has two sides to it:

A. The left side which relates to the base amt on YOUR TICKET.

B. The right side which relates to the mutuel payoff reported by the track/chartcaller that is used as a basis for calculating the AMT COLLECTED.

When the Amt Collected Tool initializes it will pickup the base wager amt that was persisted (from step 1 above) to the Data Entry Sheet and use it to auto populate the left side of the interface.

Your job as a user is is to work up the amt collected and persist it back to the Data Entry Sheet. The steps are:

a. Key in the numbers on the right side of the interface... mutuel payoff and base amount and hit the Calc Amt Coll button. This will calculate the amount you collected on the ticket.

b. Double check your amount collected and persist it back to the Data Entry Sheet by hitting the Persist To Data Entry Sheet Button.

Once you get the hang of it, it's actually fast and easy.

 

 

 

 

 

 

WagerHistory Report Generator

Operating the WagerHistory Report Generator’s SQL Expression Tool requires at least some knowledge of sql. A good benchmark is that if you can run the JCapper Data Window in sql mode then you can run the JCapper WagerHistory Report Generator with just a short learning curve.

 

The WagerHistory Report Generator is a query interface that enables the player to create and store user defined sql expressions that can be run against the WagerHistory table. The WagerHistory Report Generator also comes with a pre-built canned sql report designed for those of you with little or no interest in writing sql expressions of your own. The WagerHistory Report Generator contains much of the functionality found in the sql mode JCapper Data Window. You can use it to create, store, and execute sql expressions. You can use it to execute the pre-built canned sql report. And just as you can in the JCapper Data Window, you can break your query results out by almost all of the JCapper factors you are used to seeing in the Data Window simply by selecting a breakout factor from the factors drop down prior to executing a query.

 

The Pre-Built Canned SQL Report

Screenshots - WagerHistory Report Generator:

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen01.jpg

 

The above linked to screenshot shows the top section of the Pre-Built Canned SQL Report for my own wager history. A look at the sql expression driving the report should tell you the following:

  1. The time period covered is from January 01, 2012 through March 11, 2012
  2. The query results reflect those wagers tagged with Short Description Code HIST only.
  3. The query results reflect wagers made on individual horses (ENTRYTYPE=2) as well as wagers made on multiple horses (ENTRYTYPE=4.)

 

Running the Pre-Built Canned SQL Report

Here are the steps for running the Pre-Built Canned SQL Report:

 

  1. Select Start DateWhen the WagerHistory Report Generator is first launched, the values in the Start Date and End Date fields (located in the upper left area of the Report Generator Screen) will be auto populated with today’s date. Clicking either of these two date fields causes a standard JCapper calendar control to appear.

 

To select a start date: Click the start date field to launch the calendar control, select the desired date on the calendar control, and persist the selected date back to the report generator by clicking the APPLY button on the calendar control.

 

  1. Select End Date – Click the End Date field to launch the calendar control, select the desired date on the calendar control, and persist the selected date back to the report generator by clicking the APPLY button on the calendar control.

 

  1. Select Short Description Code – In the above linked to screenshot, I had selected HIST from the Short Description Codes drop down (located just to the right of the End Date field on the Report Generator Screen) prior to executing the report. Note that when the WagerHistory Report Generator is first launched, the values in the Short Description Codes drop down are auto populated with a list of Short Description Codes that have been previously created using the Setup Screen (discussed near the top of this help Doc.)

 

To Select a Short Description Code: Open up the Short Description Codes drop down and click the desired Short Description. Note that selecting a Short Description Code is optional and that if you elect not to select a Short Description Code, the query results returned by the executed report will not be filtered by Short Description.

 

  1. Select/Key In Optional Fields for Track, Race, EntryTypeNote that in the above linked to screenshot, the data fields for Track, Race, and EntryType contain the default values put there when the Report Generator was first launched. The Track and Race fields are blank and the EntryType drop down contains the default value 0 Both.

 

Had I wanted to limit the report to specific track codes, I could have done so by keying individual track codes into the Track field with the track codes separated by dash or minus characters like this: AQU-BEL-SAR-WOX.

 

Had I wanted to limit the report to a specific race, I could have selected the appropriate start and end date, keyed a single track code into the Track field, and keyed the race number into the Race field prior to executing the report.

 

Had I wanted to limit the report to multiple horse wagers only, I could have done so by selecting 4 Multi Horse Wager from the EntryType drop down prior to executing the report.

 

Note that the Track, Race, and EntryType fields are optional and that if you elect not to use them, reports executed by the Report Generator will not be filtered by these fields.

 

  1. Select a Breakout Factor – Behavior for selecting a breakout factor in the WagerHistory Report Generator is exactly the same as it is in the JCapper Data Window. Open up the factors drop down (located in the upper right hand side of the interface) and select the factor that you want your query results to be broken out by.

 

About the WagerHistory Module Report Generator: I made the effort to create an interface that gives you access to as many JCapper breakout factors as possible. This should be apparent at a glance. When you open up the factors drop down on the Report Generator, you should instantly recognize the list of factors as being almost identical to what is available in the SQL Mode JCapper Data Window. As I write this, more than 90 percent of the factors available to you in the SQL Mode Data Window are now available to you in the WagerHistory Module Report Generator. Also know that this part of the interface is still under construction.

 

  1. Select the Pre-Built Canned SQL Report by Name – The name of the Pre-Built Canned SQL Report is Summary By Wager Type. When the Report Generator is first launched, the Report Names drop down (located at the bottom of the Report Generator screen just to the right of the SQL button) will be populated with the characters Summary By Wager Type (the default report name.) The drop down should remain populated with the name of the Pre-Built Canned SQL Report unless you change it by clicking the SQL button (discussed in the section covering User Defined SQL Reports below.)

 

To Reselect the Pre-Built Canned SQL Report by Name: Open up the report names drop down (located at the bottom of the Report Generator screen just to the right of the SQL button) and select the default report by name: Summary By Wager Type.

 

  1. Execute the Report – With the report name for the default Pre-Built Canned SQL Report selected in the report names drop down: Click the Run Report button. This will cause the Report Generator to execute the report and display query results once the report has been executed.

 

Note: If you attempt to use the Run Reports button to execute a report other than the Pre-Built Canned SQL Report, the interface will give you a warning message telling you to select the Pre-Built Canned SQL Report by name from the reports drop down. Only the Pre-Built Canned SQL Report can be executed using the Run Report button.

 

To create, edit, or execute user defined SQL expressions: Use the SQL button (discussed in the section covering User Defined SQL Reports below) to bring up the SQL Expression Tool.

 

 

Reading the Pre-Built Canned SQL Report

The Pre-Built Canned SQL Report contains the following sections:

 

  1. Report Header Section – The report header section displays the report name, the date and time the report was executed, and the SQL expression driving the report.

 

  1. Report Summary Section – The report summary section displays query results broken out by wager type. By wager type, I am referring to specific pool such as WIN, PLACE, SHOW, WP, EXA, P3, P4, TRI, SUPER, etc.

 

  1. Report Detail Section – The report detail section displays one line for each record (or ticket) returned as part of the query results. Sorting for records displayed in the report detail section is controlled by the ORDER BY clause in the SQL expression driving the report.

 

  1. Breakout Factor Section – The breakout factor section displays the query results broken out by the breakout factor selected from the factors drop down prior to executing the report.

 

Note: Behavior for controlling start range and interval for breakout data displayed by the WagerHistory Report Generator is exactly the same as that found in the JCapper Data Window. After selecting a factor from the factors drop down, select desired start range and interval from their respective drop downs prior to executing the report.

 

 

 

 

 

 

 

Interpreting WagerHistory Reports and Retooling to Improve the Bottom Line Going Forward

Up to this point, my entire focus in this help doc has been spent illustrating how to operate the JCapper WagerHistory Module.

 

Now we come to the heart of the matter: Interpreting WagerHistory reports and retooling to improve the bottom line going forward!

 

The HIST Playing Session - Compiling Wager History Data

On January 11, 2012 I began one of the more mundane playing sessions I have undertaken since I first started betting horses. The first part of this playing session would continue until I woke up on a Monday morning some two months later in mid March and decided to call the first part of the session off. During this part of the playing session, I made several hundred wagers on horses selected by a designated group of my A UDMs. The wagers made during this playing session all had one thing in common. I recorded every single one of them in the then new JCapper Wager History Module.

 

During this part of the playing session, I put very little thought and effort into play or pass decision making. If current odds at the time the field was headed to the gate was at or above the odds or value ratio cutoffs stored in the BettingInstructions field for at least one of the A UDMs selecting the horse – I bet the horse. If current odds as post time drew near meant that none of the conditions listed in the BettingInstructions field for the A UDMs selecting the horse would be met – I passed the horse. That was pretty much the extent of my play or pass decision making during this part of the session. Unlike most other playing sessions, I wasn’t the least bit selective when it came to track weight or the physical appearance of the horse.

 

If an HDW data file was available - and if the rebate house where I have an account carried the track signal – then the track code was loaded into JCapper that day. Scratches were imported, The Calc Races button was clicked. The SQL UDM Plays Report Module was launched – and qualifying bets were made and recorded on horses selected by the designated A UDMs.

 

So that these wagers could be identified separately from others I was making during the same time period, I tagged each one with a unique Short Description Code: HIST. As you might well guess, HIST stands for history.

 

The objective for this playing session was to create a wager history data sample significant enough in size that I could use it in this help doc to illustrate a successful retooling strategy.

 

Along the way I learned and in some areas relearned the following:

 

  1. How to make a careful analysis of what I had. The Report Generator interface in the WagerHistory Module is very similar to the user interface found in the SQL Data Window. I spent a good deal of time using it to perform WagerHistory R&D. In so doing, I was able to uncover previously unseen strengths and weaknesses in my own game.

 

  1. How to use my own strengths and weaknesses to retool my game. This would involve scaling back play in areas where analysis of recorded wager history told me I was weak. It would also involve ramping up play in areas where wager history analysis told me I was strong. Strangely enough, doing this turned out to be remarkably simple. But it would have been impossible to do at all had I not done the work in the first place to create a detailed set of wager history records.

Additional Background Info About the HIST WagerHistory Sample

The time period covered in this first set of screenshots begins on January 11, 2012 and ends on March 11, 2012. There’s nothing magical about the cutoff date. March 11, 2012 was a Sunday and became the cutoff date because when I woke up the following Monday morning (March 12, 2012)  I felt like I had amassed a large enough wager history sample that maybe it was now time to try using the data to undergo a successful retooling effort.

 

Up until that morning, every day for the past two months, I had been making bets on horses selected by a handful of A UDMs without putting a whole lot of thought into play or pass decision making. The primary goal was to make bets on horses selected by my A UDMs and record the results for later analysis in the WagerHistory Module.

 

All of the bets in the query results presented in this section were tagged with a Short Description code created specifically for this part of the help doc. I used the characters HIST (which as you might guess stands for History.) The idea behind making these bets was that by making them I would be creating a wager history sample that could later be used to illustrate a solid retooling process.

 

At the beginning I was a little concerned about the cost involved in undertaking such an effort. I thought about limiting HIST wagers made to a $2.00 maximum just in case. I knew going in that wagers made would be limited to horses selected by A UDMs. I did have a history to go back to. I knew from Data Window R&D that the UDMs I’d be using were running just above break even (pre rebate) when horses selected by them found themselves racing on surfaces that I deemed to be speed favoring (pre-race.)

 

However, I did not want to limit the HIST wager history data sample to just speed favoring surfaces. I am fully cognizant of the fact that while profiling track surfaces might be a key part of my game - not every player out there is willing to (or even wants to) do the same. While establishing the HIST data sample presented in this section of the help doc, I downloaded and ran a Calc Races for every race card file available from HDW for all of the tracks carried by the rebate house where I play. Rather than worry about the speed favoring or speed tiring tendencies of the various track surfaces, if a horse was selected by an A UDM, and if the odds or value ratio cutoffs for the horse were at or exceeded min odds or value ratio cutoffs recorded ahead of time in the BettingInstructions field for at least one of the A UDMs selecting the horse - I made and recorded the bet.

 

For reasons stated above, no consideration was given to track weight. All wagers recorded as part of the HIST sample were simply awarded a Track Weight field value equal to 2.

 

The same thing applies here to evaluations related to the physical appearance of the horse. While establishing the HIST data sample presented in this section of the help doc, every wager recorded was awarded a PhysScore value equal to 3.

 

Getting back to the initial trepidation I felt about making wagers with little or no thought to play or pass decision making:

 

Rather than make $2.00 bets while establishing a HIST sample, because wagers made would be being driven by A UDMs that I had a fair degree of confidence in, I decided to play to a $2500 bank while using a bet sizing strategy where an effort would be made to size bets made on each race at or close to 1.75 percent of last known bank size.

 

I decided to do this because:

 

  1. I believed that even if the plays made came in a little under break even, once a rebate was added, there would be minimal cost involved from undertaking the effort.

 

  1. Playing to a not insignificant bank while sizing the bets using a percentage of bankroll approach would hold my interest. I knew from past experience that playing in an undisciplined manner brings with it the potential to put the entire bankroll at risk. Because $2500 was enough of a dollar amount that losing a significant part of it would matter, I would have every reason to stay sufficiently motivated throughout the session and therefore be likely to practice good discipline techniques while compiling the sample. In essence I would still be creating a Sphere and focusing on what is going on inside of that Sphere – while at the same time pretty much ignoring everything else. I’m funny like that – mostly because of the way I’m wired. For some reason I relish that type of thing.

 

Before diving into my interpretations of the HIST sample, here is the screenshot gallery again:

Interpreting the Data

In the section below I am going to post each of the screenshots from the above screenshot gallery, along with my comments about each screenshot.

 

Screenshot #1 – The Entire HIST Sample

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen01.jpg:

 

This first screenshot shows the top of the Pre-Built Canned SQL Report for the entire HIST sample. Note that there were 363 win bets and a little over 150 exotic bets recorded during the time frame when I was compiling the HIST sample. I’ll also point out that even though I keyed a start date of January 01, 2012 prior to generating the reports in these screenshots, the data making up the reports begins on Jan 11, 2012 and ends on March 11, 2012. (I state that now in the event I have reason to post screenshots of the detail section of my reports either in this help doc or on the JCapper Message Board at some later time.) Also note that pre rebate roi for the HIST sample came in at just over 0.94 for each $1.00 bet. There’s nothing special going on there. But it does establish a benchmark that can be compared against results after a retooling effort.

 

Screenshot #2 – The HIST Sample Broken Out By UDM Count Neg

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen02.jpg

 

This second screenshot shows the factor breakout data section with query results from the HIST sample broken out by the hard count of negative UDMs flagging each horse that was bet. Note that the values emphasized in this screenshot are those stored in the UDMCountNeg field of the WagerHistory table. These values are one and the same as those created by the interface while auto populating the UDM count fields whenever a Create New Record Sequence is engaged (discussed above in the Data Entry Sheet section of this help doc.)

 

There are several key points I want you to come away with after looking at this screenshot:

 

  1. I used the same set of negative expectation UDMs throughout while compiling the HIST sample. This insured that the values written to the table by the interface would be generated in a consistent manner. Had I made material changes to my negative expectation UDMs while compiling the sample, usefulness of the sample would have been compromised from a consistency standpoint.

 

  1. I allowed the interface to auto populate the UDM count data fields on the Data Entry Sheet. (See my comments as relates to maintaining consistency in item 1 above.)

 

  1. Take note of the win rate and roi for horses selected by one or more negative expectation UDMs. Then take note of the same for horses that were not selected by a negative expectation UDM. Now compare the two. Just under one third of all the wagers making up the HIST sample involve horses selected by one or more negative expectation UDMs. Given the difference in roi and hit rate after several hundred wagers: I find that to be significant.

 

My opinion after looking at this screenshot: As part of any retooling strategy, it might be wise to consider scaling back dollars wagered on horses selected by negative expectation UDMs going forward.

 

  1. About my negative expectation UDMs:

 

Rider Names: There’s no rocket science going on here. I spent some time doing Data Window R&D (breaking out the second half of 2010 BY RIDER actually) with an eye towards compiling a list of riders that the data said were underperforming the norm. There are about 180 rider names on my list. A little time spent using the JCapper Name Selection Tool made short work of this project. Truth be told I really should go back and bring the list current but I haven’t touched it since it was first created. If you ever noticed the grey font negative expectation UDM named x_belowParRiders2010 on any of the HTML Reports I posted on the JCapper Message Board and wondered what that UDM was all about – now you know.

 

Distance Challenged Horses: This is another minor category of negative expectation UDM that I use. Here I am identifying the older horse, using HorseType, that is a confirmed router switching to a sprint distance today. I have a second negative expectation UDM that flags such horses returning off of a lengthy layoff - the idea being that such routers are seldom win candidates in their return sprint race. I have a third UDM that deals with sprinters stretching out. Again older horses confirmed as belonging in their distance category – trying to push the envelope by stretching out. Hey, no one is more painfully aware that every now and then horses flagged by this type of negative expectation UDM can and do step up to surprise when stretching out or cutting back – often paying a big mutuel in the process. However, the data in the HIST sample suggests that some scaling back in betting appears to be in order when it comes to distance challenged horses

 

Vet Scratches: The Data Entry Sheet Interface in the WagerHistory Module recognizes Vet Scratches and treats them the same as if the horse were flagged by a negative expectation UDM. My Scratch BOT settings in the Enhanced Settings Module are set to make Scratch BOT parse all tracks in the XML rather than only those tracks I might currently have loaded into JCapper. That means whenever I click the XML button, Scratch BOT is picking up every Vet Scratch available in the XML and writing it to my TripNotes table – where it can be picked up when UDM profiles are generated on race day. I realize not everyone out there is doing this. Given that the values shown on this screenshot do reflect Vet Scratches data picked up by the interface during live play, if you are not operating Scratch BOT in such a way that you are picking up as many Vet Scratches as possible: You might want to rethink your way of doing things.

 

 

Screenshot #3 – The HIST Sample Broken Out By CompoundAP Rank

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen03.jpg

 

This third screenshot shows the HIST sample broken out by CompoundAP Rank. Note the win rate and roi in the data sample for horses ranked fifth or worse in CompoundAP. In my opinion, some degree of scaling back appears to be in order when it comes to betting horses lacking in early or late pace ability – or some combination of the two.

 

Note: The factor breakout section of the report screenshot displays CompoundAP as SQL-F18 Rank. Behavior for SQL F-Factors in the WagerHistory Report Generator is exactly the same as that found in the JCapper Data Window. Clicking the Display Factors button in the upper right area of the Report Generator Screen causes the interface to display the user’s SQL Factor Setup. Re-clicking the button causes the interface to redisplay whatever data was previously displayed in the module’s viewing area. In this case, CompoundAP is the JCapper factor assigned to F-Slot number 18 in my SQL Factor Setup. After operating in SQL Mode for a time, you will likely commit your SQL Factor Setup to memory and seldom find yourself clicking the Display Factors button.

 

Screenshot #4 – The HIST Sample Broken Out By UDM Count (B-Neg)

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen04.jpg

 

The fourth screenshot shows the HIST data sample broken out by UDM Count (B-Neg.) What is UDM Count B-Neg? It is simply the number of Negative Expectation UDMs flagging the horse wagered on subtracted from the number of B UDMs flagging the same horse. Note the weakness indicated by the data when the number of B UDMs flagging horses wagered on fails to outnumber the count for Negative Expectation UDMs.

 

Note: Results will vary here from one player to another based on the number and factor makeup of both Negative Expectation and B UDMs. (Your own mileage may vary.) However, based on the data in the HIST sample for my own UDMs, a good retooling strategy would appear to involve scaling back betting on horses where the number of Negative Expectation UDMs flagging the horse outnumbers the count for B UDMs flagging the same horse.

 

 

Screenshot #5 – The HIST Sample Broken Out By CPace Numeric Value

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen05.jpg

 

The fifth screenshot shows the HIST sample broken out by CPace Numeric Value.

 

Note: CPace is the factor sitting in slot number F-20 in my SQL Factor Setup.

 

Note the area of weakness in the sample results for horses with low CPace numbers. Rather than apply something akin to a blanket cutoff, I rolled up my sleeves and spent some time at the Data Window doing R&D. My thought process went something like this: If I take shortcuts in the retooling process - if I just glance at the data and say to myself: “From here on out any horse I bet on needs to have a CPace value of at least 160” - Operating in that manner has me ignoring the following fact:

 

Quality of horses in competition varies greatly from one track to another and from one class level to another.

 

Think about it for a second. Older allowance males at Gulfstream have every right to earn higher E1 and E2 pace figs (and therefore earn higher CPace numbers) than 5k claimers at tracks running lesser quality stock such as Beulah and Mountaineer.

 

Past experience has taught me that ignoring facts like the above has a way of aiding the player in generating selections that fail to perform well going forward.

 

In my R&D I ended up establishing min CPace values based on AgeOfHorse, Sex, ClassDescriptor, and Track Code. I was liberal (hopefully not overly tight) in establishing cutoffs – but cutoffs were established and applied just the same.

 

 

Screenshot #6 – The HIST Sample Broken Out By UDM Count (A-Neg)

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen06.jpg

 

The sixth screenshot shows the HIST data sample broken out by UDM Count (A-Neg.) My comments for this factor mirror those I wrote about UDM Count (B-Neg) above.

 

What is UDM Count A-Neg? It is simply the number of Negative Expectation UDMs flagging the horse wagered on subtracted from the number of A UDMs flagging the same horse. Note the weakness indicated by the data when the number of A UDMs flagging horses wagered on fails to outnumber the count for Negative Expectation UDMs.

 

Note: Results will vary here from one player to another based on the number and factor makeup of both Negative Expectation and A UDMs. (Your own mileage may vary.) However, based on the data in the HIST sample for my own UDMs, a good retooling strategy would appear to involve scaling back betting on horses where the number of Negative Expectation UDMs flagging the horse outnumbers the count for A UDMs flagging the same horse.

 

 

The Retooling Process Summarized

At this point I’ve hopefully posted enough screenshots and enough in the way of comments to have communicated what the retooling process is all about.

 

Your job throughout the retooling process is to:

 

  1. Use the interface to record a significant number of actual wagers. Best practice in my opinion would be to get in the habit of recording every single wager that you make. Always insist that data recorded in the WagerHistory table be compiled in such a way that consistency in the data is maintained throughout each sample. Consistency in compilation across multiple samples? Even better.

 

  1. Analyze your wager history data carefully. Your primary objective should be to identify both strengths and weaknesses in your play.

 

  1. Constantly analyze your results. Understand that the analysis process isn’t a one time thing. Best practice in my opinion would be to turn your analysis process into something that is both constant and ongoing. Do that and you will find yourself: 1.) Constantly learning about the game as it slowly evolves in front of you. 2.) Constantly learning about your own strengths and weaknesses as a player.

 

  1. Take corrective action. Don’t be afraid to scale back your betting in areas where your analysis suggests you are weak. Don’t be afraid to ramp up your play in areas where your analysis suggests you are strong. But before so doing, consider validating both strengths and weaknesses using the same validation technique you would use to evaluate the effectiveness of a new business UDM: by confronting it with fresh races using a validation sample.

 

  1. Use all of the major schools of handicapping thought covered by the factors in the JCapper program. Don’t limit yourself to just the six areas pointed out by my screenshots. My own retooling efforts involve identifying strengths and weaknesses gleaned from looking at lots and lots of screenshots just like the six that I posted above. The key difference between the six that I posted and the ones that I didn’t are the names of the factors used when breaking out results data. Know that in my own retooling efforts every major area covered by the factors in the JCapper program is fair game: form, early speed, late speed, ability from speed figures, class, pace matchup, ability as indicated by power ratings, the interplay amongst my own UDMs, value and odds based ratios, factors tied to the race itself, track profile analysis, and my own assessment (visually) about the physical condition of the horse. Also know that in my retooling efforts, I strive to consistently apply a nearly identical thought process to each and every factor evaluated. That includes the six areas that are covered above – as well as the many other areas made available by the interface I might choose to evaluate.

 

 

Retooling After the HIST Playing Session

When I woke up that Monday morning in the middle of March, 2012 after having compiled wager history data for horses selected by a handful of A UDMs spanning a two month period at all tracks available for me to bet, I realized that I probably had amassed enough wager history data to try a retooling effort.

 

I spent the next few days running reports in the WagerHistory Module. I pasted the more telling ones into a text file (Notepad) so that I could look at them later. Armed with insights gleaned from data found on those reports, I began the retooling effort in earnest.

 

The first area that I focused on was trying to make some sense out of the interplay amongst my own UDMs. What did the data say about horses selected by a single A UDM as opposed to horses where all the A UDMs seemed to be converging? What did the data have to say about the number of B UDMs flagging a single horse? What about the combined number of A and B UDMs? How did Negative Expectation UDMs fit into the picture? This was brand new territory for me. Needless to say it took me a while – but eventually, after running and looking at lots of wager history reports, the many interactions amongst my A, B, and Negative Expectation UDMs began making sense to me.

 

One of the most glaring areas of weakness in my game turned out to be situations where the Negative Expectation UDMs selecting a horse outnumbered the A and/or B UDMs selecting the same horse. This one was a real eye opener for me because it was something I had never considered before.

 

Two implementation strategies occurred to me.

 

The first strategy I considered involved writing out lines of sql to capture the factor constraints found in each of my Negative Expectation UDMs, wrapping these inside of parenthesis characters, placing the keywords AND NOT immediately to the left of the wrapped up expression, and pasting the entire thing (a fully encapsulated piece of sql that captured the essence of  a negative expectation UDM) directly into the body of the SQL UDM Definition driving each of the active A and B UDMs I was using.

 

If I did this, I stood to completely avoid betting on horses selected by any negative expectation UDM. All of my A and B UDMs would simply fail to fire on race day whenever conditions causing the negative expectation UDM to fire existed. Horses selected by both A and negative expectation UDMs would be a thing of the past – as would horses selected by both B and negative expectation UDMs.

 

However, I decided against this strategy. Maintenance going forward would be a bear.

 

What if at some future point I decided to rework my list of underperforming riders? Or decided to make some other change to a negative expectation UDM? After changing the sql for the negative expectation UDM itself, I would then have to rework the sql for every active A and B UDM just to effect the same change. So instead of editing the sql from one negative expectation UDM each time a change was warranted - I was now setting myself up to be editing 15-20 UDMs each time a change (any change) to a negative expectation UDM was warranted.

 

Further, each time a new A or B UDM might be created, I would be required to scour the UDM Definitions of existing A and B UDMs so that I could find and lift the negative expectation part so that I could then paste it into the body of the new UDM.

 

I instantly disliked the thought of operating in this fashion. It could easily turn out to be a maintenance nightmare. No thank you.

 

From an ease of maintenance/best practices standpoint, I decided to continue maintaining positive and negative expectation UDMs as separate entities.

 

The second strategy I considered would be relatively simple to implement. What if I took strengths and weaknesses uncovered during wager history R&D and simply integrated that new knowledge into my play or pass decision making and bet sizing during live play?

 

The only thing implementing that kind of retooling required would be coming up with a set of new rules to be added to what I was already doing during live play. The idea instantly resonated with me, and it was the implementation strategy I decided to use.

 

These may sound simplistic, but here’s what I came up with:

 

  1. Scale back bet size significantly (or simply pass) if the A UDM horse is selected by even one negative expectation UDM.

 

  1. Scale back bet size somewhat if the horse is overmatched pace-wise (based on my own combination of CompoundPaceFit, CPace, EarlyConsensus, CompoundLate, and LateConsensus.)

 

  1. Scale back bet size somewhat if the horse has CPace numeric value lower than what my R&D turned up as par for the level. No, I haven’t published anything remotely resembling a CPace par. I doubt I ever will. But it’s obvious from looking at track code, age of horse, and class descriptor specific data samples broken out by CPace numeric value that such a thing does exist.

 

  1. Scale back bet size somewhat if the horse is weak vs. its field in two or more of the following: FormConsensus, EarlyConsensus, LateConsensus, FigConsensus, ClassConsensus, PowerConsensus, or UPR. In other words, if the saddle cloth number for the horse isn’t prominently featured in the race summary at the bottom of the SQL UDM Plays Report: Reduce the bet size.

 

  1. Pass if current odds or value ratios at decision time are lower than that recorded in the BettingInstructions field.

 

  1. Scale back bet size significantly when physical appearance of the horse is suspect. Trust your eyes.

 

  1. Scale back bet size significantly when track surface figures to negatively impact the horse in running its race. Trust your eyes based on what you’ve seen so far while watching today’s races. Also trust the Track Weight Report.

 

  1. Scale back bet size significantly when race shape figures to negatively impact the horse in running its race.

 

As simple as some of those may sound, implementing them during live play proved to be a difference maker.

 

 

 

 

 

The HIST Playing Session Continued – After Retooling

The screenshots posted in this section show a user defined report that I created using the Report Generator’s SQL Expression Tool. The stored sql expression used to generate these reports is as follows:

 

SELECT * FROM WAGERHISTORY

           WHERE (ENTRYTYPE = 2 OR ENTRYTYPE = 4)

           AND SHORTDESCRIPTION = 'HIST'

           AND UDMCOUNTNEG = 0

           AND TRACKWEIGHT > 0

           AND TRACKWEIGHT <= 2

           AND [DATE] BETWEEN #03/16/2012#

           AND #05/15/2012#

           ORDER BY [DATE] DESC, TRACKCODE, RACENUMBER, SHORTDESCRIPTION

 

 

The wagering activity shown in the screenshots below is on horses selected by the same basic set of A UDMs used to select horses in the HIST playing session discussed above. The key difference between the wagering activity in the first part of the HIST sample and the wagering activity presented here is that these wagers were made after the retooling process (discussed above) was implemented. These screenshots reflect wagering activity beginning on March 16, 2012 and ending on May, 15, 2012 – the two month period immediately following implementation of the retooling process.

Screenshot #12 – SQL Expression Tool:

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen12.jpg

 

This screenshot shows the Report Generator SQL Expression Tool. Here I’ve used the SQL Expression Tool to create and store a sql expression that can be used to generate of reports that reflect wager history after the retooling process (described above) has been implemented.

 

Screenshot #13 – Wager History After Retooling:

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen13.jpg

 

This screenshot shows the top section of the newly created custom sql report. Note that wager history on this report spans the two month period (March, 16 2012 through May 15, 2012) immediately following implementation of the retooling effort (discussed above.)

 

Screenshot #14 – Wager History Broken Out By Surface:

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen14.jpg

 

This screenshot shows wager history spanning the two month time period (March, 16 2012 through May 15, 2012) immediately following implementation of the retooling effort (discussed above) broken out by Surface.

 

Note: Prior to executing the report by hitting the Execute button on the SQL Expression Tool, I had selected Surface Today as my breakout factor in the Factors Drop Down on the Report Generator interface.

 

Note: These A UDM plays appear solid on dirt surfaces but weak on the turf. Is this the result of a short term aberration? Or might it possibly be the start of a new longer term trend? In my opinion, best practice for analyzing wager history involves making the analysis process something that is ongoing and constant. At the very least, this (new) area of (potential) weakness bears watching going forward.

 

Screenshot #15 – Wager History Broken Out By Distance Shift:

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen15.jpg

 

This screenshot shows wager history spanning the two month time period (March, 16 2012 through May 15, 2012) immediately following implementation of the retooling effort (discussed above) broken out by Distance Shift.

 

Note: Prior to executing the report by hitting the Execute button on the SQL Expression Tool, I had selected Distance Shift as my breakout factor in the Factors Drop Down on the Report Generator interface.

 

Note: As part of the retooling process, I decided to pass horses selected by even one negative expectation UDM. This would include horses identified as distance challenged when stretching out or cutting back in distance while moving from one broad distance category to another (sprint to route or route to sprint.).

 

I draw your attention to weakness shown on this report for starters at the edges: Horses stretching out and/or cutting back 1.5 or more furlongs in distance.

 

Performance for starters at the edges on this report is for horses that stayed within the same (broad) distance category as their previous start. This represents a slightly different category than starters eliminated through use of the distance challenged negative expectation UDMs discussed above.

 

For example, both printers cutting back from a 7f race to a 5f race and routers stretching out from an 8f race to a 10f race are shown on this report.

 

At this stage, there really isn’t enough data on the report to work with (just 8 starters at the edge in total) for me to consider further corrective action. That said, performance at the edges as relates to distance shift still bears watching going forward.

 

Note: Horses cutting back a half furlong in distance are showing considerable weakness on this report. Is this a short term aberration? Or might it be part of a (larger) big picture trend?

 

Screenshot #15b – Wager History (Entire HIST Playing Session) Broken Out By Distance Shift:

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen15b.jpg

 

This screenshot shows a larger data sample than the preceding one. Here the report spans the entire HIST playing session (Jan, 11 2012 through May 15, 2012) broken out by Distance Shift. I have (ever so crudely) underlined the line on the report for horses cutting back one half furlong in distance. This line is weaker than the others on the report but still positive. Based on what I see I am willing to concede the possibility that weakness for this same line in the preceding screenshot could stem from a short term aberration. The fact that this (weaker) line occurs in the middle of the report rather than at the edges leads me to suspect this. I’m reluctant to take corrective action at this point – but will watch this area going forward and revisit it in the future as more data becomes available.

 

Screenshot #16 – Wager History Broken Out By Distance:

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen16.jpg

 

This screenshot shows wager history spanning the two month time period (March, 16 2012 through May 15, 2012) immediately following implementation of the retooling effort (discussed above) broken out by Distance.

 

Note: Prior to executing the report by hitting the Execute button on the SQL Expression Tool, I had selected Distance as my breakout factor in the Factors Drop Down on the Report Generator interface.

 

Note that horses competing at shorter sprint distances are showing weakness on this report. Is this a short term aberration? Or might it be part of a (larger) big picture trend?

 

Screenshot #16b – Wager History (Entire HIST Playing Session) Broken Out By Distance:

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen16b.jpg

 

This screenshot shows a larger data sample than the preceding one. Here the report spans the entire HIST playing session (Jan, 11 2012 through May 15, 2012) broken out by Distance.

 

I have (ever so crudely) circled the lines on the report for horses competing at shorter sprint distances. These lines are weaker than the others on the report but are still positive. Based on what I see (for 120+ plays spanning these lines) I am willing to concede the possibility that weakness for these same lines in the preceding screenshot could stem from a short term aberration. However, these (weaker) lines occur at one edge of report rather than in the middle. That can often be a good indicator that weakness seen in one sample will continue well into the next. This has me concerned. While not ready to take corrective action just yet I WILL be watching this area very closely going forward (more closely than the Distance Shift area discussed in the previous screenshot pair.)

 

Screenshot #17 – Wager History Broken Out By Class Descriptor:

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen17.jpg

 

This screenshot shows wager history spanning the two month time period (March, 16 2012 through May 15, 2012) immediately following implementation of the retooling effort (discussed above) broken out by Class Descriptor.

 

The handful of plays for CO and AO races shows weakness. However, there is insufficient data (not enough plays) on the report to make me feel comfortable taking corrective action at this point.

 

Screenshot #18 – Wager History Broken Out By Compound PaceFit Numeric Value:

http://www.jcapper.com/messageboard/avatars/WagerHistReportGen18.jpg

 

This screenshot shows wager history spanning the two month time period (March, 16 2012 through May 15, 2012) immediately following implementation of the retooling effort (discussed above) broken out by Compound PaceFit Numeric Value.

 

Looking at the report, I see weakness at the lower edge of the data sample – where Compound PaceFit is less than 40. There aren’t a whole lot of plays to work with but I am troubled by what I see here. If you’ll recall, item number two from my retooling strategy reads as follows:

 

2. Scale back bet size somewhat if the horse is overmatched pace-wise (based on my own combination of CompoundPaceFit, CPace, EarlyConsensus, CompoundLate, and LateConsensus.)

 

The numbers on the report are telling me that room for improvement exists. From here, I am willing to take a harder stance and alter rule number two from my retooling efforts to read as follows:

 

2. Scale back bet size significantly (or simply pass) if CompoundPaceFit numeric value is less than 40.

 

 

Summary

When I think about record keeping in terms of best practices it occurs to me that review of wager history data is not optional. It should be an integral part of your game. Nor is record keeping and analysis of wager history data a one time thing. Proper record keeping is something that is both constant and ongoing.
