Hi..

What would consider an acceptable UDM?

Based on 12 months, would you take it if it has 1,2,3 etc of negative ROI or on a positive ROI for the 12 months?

A lot of times if I have several months of negative, it's because of a specific track or two. Might want to look at it by track to see if that can exclude any big losers.

For me, I'll take a few months of bad ROI, but it can't be a big loss during the bad months.

Using the Data Window in sql mode, one of the tests that I subject my UDMs to is to break the data out by RGN.

RGN is a randomly generated number between 1 and 100 assigned to each starter by the Database Builder at the point in time when the StarterHistory table is populated.

Below are two data samples that illustrate what I am talking about.

The first data sample is a UDM from its development data set:

query end: 3/8/2013 12:23:53 PM

Note that in the above data sample, the RGN data is broken out in 20 separate rows - each row having an increment of 5 points each. Also note that 17 of the 20 rows (or 85%) are individually profitable.

Attempting to relate that to months - if live play were restricted to only those plays generated by the single UDM used in the above sample AND IF THE UDM'S ACTUAL PERFORMANCE DURING LIVE PLAY REMAINED ON PAR WITH THE PERFORANCE SEEN IN THE DEVELOPMENT SAMPLE, ADMITTEDLY A TALL ORDER:

Each month would have an (approximate) 85% chance of profitability. Put another way: The player's expectation would be an impressive 10.2 profitable months out of each 12 (something I have not personally been able to achieve.)





Here is the same UDM run through the Data Window broken out by RGN... except this time, the time period of the sample is that after I began using the UDM to generate live plays:

Note that in the above data sample, the RGN data is broken out in 20 separate rows - each row having an increment of 5 points each. Also note that 14 of the 20 rows (or 70%) are individually profitable.

Attempting to relate that to months - if live play were restricted to only those plays generated by the single UDM used in the above sample - which this time reflects actual performance seen during live play:

Each month would have an (approximate) 70% chance of profitability. Put another way: The player's expectation would be (approximately) 8.4 profitable months out of each 12.


Based on personal experience using my own UDMs, 8.4 months of profitable play out of each 12 is realistically achievable.

Ideally I would love to be profitable EVERY month - but the reality is I have never been able to achieve that.

Thxs Jeff...another reason to go via SQL Mode, as RGN is not in Playlist Mode
