Update: Results

[rmath]

I know have 240 races in my testing of the RX3 factor (which uses Profit Line ratings to obtain these ratings.)
These races range from 5.5f- 8.5f non maiden, dirt races
with 8 or more betting interests
I used the best of last 3 pacelines with no changes.
My goal was to simply see how well this rating would do in getting the winner in the top 5 and how often the exacta was in the top 5 RX3 rating.
Wins:
RX3: 1)67
2) 51
3) 47
4) 36
5)20
Total: 221 .92 wins
Exactas: 180 .75
37 of these exactas involved the # 5 RX3 horse ( 15% ) of the total.
Only 6 of the 37 were 4-5s (this is only 2.5% of the exactas)

I made no judgements at all in this study.
While I do not recommend using only the RX factor as a stand alone
factor , it is a simple & easy way to get a starting point for the main contenders in a playable race.

I believe Ted has done a great job on these improvements and I would like to thank him for allowing me to be one of the testers.

Good skill to all.
