What's your take on raceourse gradings when compared with form?
Rob,
Not sure if that question was aimed at me or just a question for all?
I don't look at the track as any sort guide to class. A class 100 is a class 100 wherever its run and is judged solely on that. Of course the course can make a big difference but that is based on the lay out of the track and that is the only time the actual track comes into the equation for me.
Of the tracks listed by Chesham I would have to agree about the position of Epsom is vastly out of kilter with my findings. In the last four seasons I have only listed 22 races strong enough to gain entry on the d/base. Doncaster has 46, Sandown 35 etc. As getting the NH d/bases up to date was more than a little boring I then did a quick check on the top rated ability horse that gained that rating at Epsom and have to say it was very disappointing I could only find one top rated winner, ok I think there were only about 20/25 races.
As Chesham says those down the field may perform better next time, because the course does not suit their galloping style, and I found quite a few Mark Johnston winner this way.
While working on the d/bases I have been looking at ways of trying to make the ability rating even stronger. I looked at races where the favourite finished close up, where the top OR was close up and didn't find any improvement. I then tried using the average OR of the field and the horses that finished close up and that didn't make much difference.
All in all a frustrating day
Be Lucky
