I would like help with speed ratings, for example if a horse ran 10 furlongs and another 7 furlongs.
I can give each horse a rating but I dont know how to adjust for the distance they ran.
Can anyone help please.
To answer your specific question I adjust all race distances to a mile
So if the 7F race was 3.5 seconds slower than standard, divide that by 7 and times by 8 = 4 seconds per mile slow
if the 10F race was 5 seconds slower than standard, divide by 10 and times by 8 = 4 seconds per mile slow
then work out your ratings on the basis of the ‘per mile’ time so you’re always comparing like with like
