SpeedForm Master Rating (last 6 races) + Recent Form With Good PRB (last 2 months)
Percentage of Rivals Beaten (PRB) PRB tries to take races hierarchy a step further and produce a sliding scale of performance for every runner in a race based on where they finished. FOR EXAMPLE : The 4th placed horse's PRB in a 12-runner race would be calculated as:
(12 – 4) / (12 – 1)
= 8 / 11
= 0.73 (or 73%)
Good PRB = 0.75+ (or 75+%) atleast 1 race in last 2 months
