User Race Flags


The purpose of the User Race Flags (URF) feature is to enable you to flag races that have certain characteristics of your choice in order to later analyse only those races with the GTX System Developer.

There are ten flags on the User Race Flags pad, which is located on the Race Details Bar, like so...

Run your mouse pointer around inside the pad and you will see the flags pop up, together with their tool tip descriptions. A flag is selected by clicking on it. The image above shows that Flag A has been selected and the mouse pointer is hovering over Flag B.

Flags can be configured manually (!) or via the GTX System Developer.

You decide what each flag represents in your GTX, but for this demonstration we will use Flag A to flag all races with seven runners where there was an odds-on favourite and no first starters.


Entering the URF via the GTX System Developer


Step 1: Clear the Flag that you wish to assign for a given date range in case it has previously been used.

On the GTX Menu Bar, select User, then Clear Flags. In the Clear User Flags box that opens, select the flags you want to clear, choose the selected dates from... option and select the date range over which you want to clear the flags.

Then click the Clear button.




Step 2: Open the System Developer, choose an empty system and assemble the race rules and any other limiting rule. In this example, we have only three rules, like so:

Current rules for: empty system

include if Field Size = 7
include if First Starters = 0

include if SP Price between 0 and 0.9

The above rules eliminate:
..every race where there were more or less than 7 runners
..every race that included a first starter
..every race where the SP of the favourite was more than $2 (odds-on)


Run that system over some data and check that the resultant selections are what you expect, that is that they match the rules. If all is as it should be, then in the option pane at the right of the System Developer, tick the 'set URF' option and enter A into the text box.

Then run the system over the date range in which you want to set the User Race Flag A.

This will result in Flag A being set for every race in the date range where there were exactly seven runners, each of which has previously started and the SP favourite was odds-on.

Save the system and exit the System Developer.

Closing the System Developer will automatically deselect the 'set URF: A' option, but if you go straight to the next step without closing the System Developer, make sure you manually deselect the option.

To analyse all races that have Flag A set

Open GTX and the System Developer. Before going further you nead to decide if you are going to employ the Race Profile Database (RPD). If you do want to use it, you either need to have previously created it to include the date range of races that you want to run your system over, or you need to create it now. See How to create and update the RPD.

If you don't want to employ the RPD, make sure it is not selected.

Then create a new system with only the following rule:


Current rules for: empty system

include if User A

Then select your preferred 'Analyze by' option (in our example at right, we selected 'SP Rank), and run the system over the date range that encompasses the saved flags.

The result of our sample analysis reveals that of the 1046 flagged races in the selected date range, 57% of SP favourites won, 17% second ranked selections won and only 2% of 6th and 7th ranked favourites won.  


The main point of using the Race Flags in this manner is that you have created a subset of races, as defined by the particular flag, that you can then analyse further with the System Developer which would then query only the subset, without needing to again analyse all races in your date range. For example, if you then want to analyse just the favourites you will need to include an additional limiting rule to eliminate all selections that were not favourites, (ie not SP Rank 1).

That rule will be 'include if SP Rank = 1'. See image at right.

And in this example, we have chosen to 'Analyze by..' Race Area

Be aware that the 'rules' we have used above to define Flag A are just one example of the options available to you to create your flags
