Using the BRIS Track Bias Stats for Tampa Bay 9 on Wednesday, March 16th (Free PP attached) I'm trying to figure out the
true Impact Values for Posts 2 and 3.
Total Races = 124
Rail Impact Value = 1.41 Win = 16%
1-3 Impact Value = 1.15 Win = 13%
4-7 Impact Value = 0.93 Win = 10%
8+ Impact Value = 0.90 Win = 9%
The way I read these stats is that the Rail has an IV of 1.41 and Win % of 16; and that Posts 1 to 3 inclusive have an IV of 1.15 and a Win % of 13.
How would you calculate the IV and Win % for
Posts 2 and 3 only not 1,2 and 3 as the stats seem to show.
Any input would be appreciated,
Trotter
