Predictability Index (harness)

Explanation of Predictability Index Value Calculation:

	Base Index Value (all horses start at this level) = 90

	Deductions are made if the following “uncertainties” exist…..	Value

1	If the horse’s most recent performance was in a qualifying race	-10
2	If the horse has not raced in over 21 days	-10
3	If the horse broke stride (without interference) in its last start	-10
4	If the horse’s last start was on a different track than today’s race	-10
5	If the horse’s last start was on a track for which there is limited statistical data	-10
6	If the horse has one or more recent lines which are considered poor performance	-10
7	If the horse does not have at least two recent lines which are considered “clean” and useable	-10
8	If the daily track condition variant of a previous race was estimated using track statistical data	-10
9	If it is a trotter. Trotters are statistically less predictable than pacers.	-10

	Minimum Total Predictability Index	0
	Maximum Predictability Index (no deductions)	90

	Best Bets	100
	When the point spread between the top pick and the second pick exceeds a certain amount (generally 30 points)
	combined with several other factors (one of which is that the horse has a base adjusted index of 90 (80 if a trotter)
	then we add 10 Points (20 if a trotter) bringing the total PRE to 100! This is considered a highly reliable race to bet!!
