Class ratings in At The Races Posted July 6 On 7/3/2022 at 3:12 PM, richard-westwood said: The argument that always ..always pops up is course adjustment so straight off I needed to factor that in .... then you have your class rating itself ....then an adjustment for where you finished .... Each one of course has its pitfalls and I'm sure will require a bit of debate but it's not impossible and it's a worthwhile thing to try and do As always, a very interesting debate. I think I've attempted to use courses before to determine class but it wasn't particularly successful. You could have the situation where a horse that ran in a class 6 handicap at Epsom has a rating of 16 compared to a horse that ran in a class 1 listed race at Bath which would have a rating of 4. This seems illogical. Is it not easier to simply use the class of the race last time or the value of the race ?
