osulldj, I think that is a good way, but as La Mer said, "all OK when looking at the class issue in the group restricted entry type of races, but it's not as easy for some".

I think prize money is the best way to determine class...I usually look at the horses last run and match that prize money with todays race prize money. If today's prize money lower then last race prize money by atleast $10,000 then he is running a easer class race. Example: Todays race prize money $50,000 and last start prize money $150,000. I'm more confident about them if they ran a place last start or short margin, 4th and up position. Anyway thats what I do. Good luck guy's.
