Hi Chris,
Just a thought, you use price predictor and cyberhorse.
I know it's hard to believe with all my go to the track stuff, but I also have price predictor and import cyberhorse daily, because obviously I can't get to the track everyday.

I don't use price predictor to work out (systems) but to easily import cyberhorse.

In their database they have their own ratings for the race and I have noted their top 4 rated have a very good strike rate, with some at very good odds.

Have you ever looked at these for a basis for a system?

Cheers
