RDSS uses the formula:
100 - 6/65*100 = 100 - 9.23 = 91% rounded.
A horse with 6th fastest workout time out of 65 horses that day and distance worked faster than 91% of the rest.
Then again, a horse who finished 1 out of 11 also gets about a 91%. Of these 2 different horses - or the same horse on 2 different days - if they both worked over 5 furlongs but 6/65 got a speed rating (measure of final workout time) of 80 (slower time) and 1/11 got a SR of 90 (faster time) -- which indicates the better effort? The 6/65 effort worked faster than 59 other horses, while the 1/11 worked faster than only 10 others. Does it matter?
I ask because this is a discussion Mitch and I have been having and I am wondering if the relative presentation of such figures can be tweaked. This readout has been in RDSS for years and Mitch is presenting new ways of using it to measure improvement, particularly in Maiden and longer layoff scenarios.
