Oh i doubt there will be anything i would/could contribute to help you along your path, but you've given me a good chuckle that you thought i could. It just goes to show what i know, i assumed (wrongly) that any speed rating on a horse would have to be at the distance it was racing at, first and foremost. Thinking as i type and have just had a winner in the 515, (yippee) i use an example of the poor horses that are not quite sprinters, 5/6f, and can't last a mile, but excel over 7f and as far as i know, there are no classic's or decent races over that distance. (sorry if i'm wrong on that) To me, taking speed figures from 6f races and 8f races when their best distance is 7f, just seems strange. What i've just said is just an example of course and not explained very well, but i hope you get what i'm getting at? Seems to be coming along anyway and you've already had a few winners from it, just think how good it will be when you have all your facts and figures input into it...will be a gold mine!!!
