Hi All,

Was playing with these lovely filters and found myself sliding down that slippery slope once again (4 horses started at provincial meetings at distances over 1800 and all lost so that must be a good filter.) So to cut a long story short (which you may be able to tell I can't do ) I "Chi'd" the filtered results.

I have looked at the following filters based on our results.
- Maiden/Non-Maiden
- Starting Price Under $3/ $3 - $4.9/ $5 and Over
- Metro/Provincial
- Metro Under $5/ Provincial Under $5
- Distance <1600/>=1600

Using Chi Squared, only 2 filters improved the results and only one of those filters improved the results greatly, and one filter showed slightly lower results.

For the purpose of testing I will now use 4 systems.
1. The Original System
2. SP under $3 System
3. Provincial SP under $5 System
4. Distance < 1600m System

We will recommence the testing period as of today, run each for 100 selections and then Chi and see.

Cheers
Brett
