Xanadu ,

Actually i didn't really change that much except for the fact i totally disregarded weight as a factor.

I also altered my class ratings , which actually differ quite significantly in some ways to other "experts" class ratings.

But you are definetely correct about class , thats the most important factor in my ratings.

I also changed the runs i rate for each horse , i used to rate the last 4 runs , but i changed that to the best 4 runs from the last 6 starts within 500m of the race distance , if that makes any sense.

The plan i just created is a set of rules for the top rated horse , if they pass they become a selection. The rules take into account , Consistency , Barriers , Jockeys and Trainers and of course Class.

Hope that helps Xanadu.
