Beaten Lengths (Finish Position Last Start)

Q. Jeff, How do I add Beaten Lengths (Finish Position Last Start) to a UDM?

A. Beaten Lengths (Finish Position Last Start) is one of the factors controlled by Dynamic Filters. Before we go any further I need to make something clear. For horses that won their most recent start Beaten Lengths (Finish Position Last Start) is expressed as a negative number. For horses that finished 2nd or worse in their most recent start Beaten Lengths (Finish Position Last Start) is expressed as a positive number.

The reason I designed things this way was to allow UDMs to differentiate beaten lengths of winning horses from horses that didn't win. It prevents mixing and matching of two different things.

Example: You want to create a UDM that only flags horses that won their most recent start by at least 3 lengths. Max beaten lengths = -3.

Example You want to create a UDM to flag horses that finished within 3 lengths of the winner in the most recent start. Max beaten lengths = 3.

Adding Beaten Lengths (Finish Position Last Start) to a UDM - here's how:

1. In the factors drop down of the UDM Wizard, select FILTERS as your factor and click the Dynamic Filter Tool button.

2. In the Dynamic Filter Tool, select Beaten Lengths (Finish Position Last Start) as your factor. Select ALL classes and ages as your context. Going with the above example where we want to flag horses that won their most recent start by 3 or more lengths, select MXN (max neg value) as your behavior. Then select Prompt for Value and key in -3 as your value. The filter code !ALL!MXN3 will appear in the small preview window. Click Add Filter to move the filter code !ALL!MXN3 to the big preview window. Then click Save and Close to write all of the filter codes in the big preview window to the UDM Definition.

At this point the UDM should only flag those horses that won their most recent start by 3 or more lengths.

Running the UDM through the Data Window should produce results that look very much like this:
