I progressed to form and weight and stayed there even when some changed to pace i didn't change, i dropped the weight as the limit increased, over the past 12 months i find my ratings only work in higher grade races these days as i think you still need form to win those races.

On the Punters Show the other day Marc talked about fitness and distance change and it did make sense and got me thinking, also the other fact that horses often repeat performances year in year out if trained the same way i need to come up with a few other ideas.
