"Using a system to triangulate a horse like that quickly allows to isolate the best chances. Most professional punters work along these lines; create a short list and then finalise bets on additional work"

As simple as this sounds, its taken me some time to get this point but I am close to what I think might be workable strategy along these lines now using a couple of sets of ratings and a price filter. What I don't have is a database to check that it works over the longer run.

Thank you for the clarification Michal.

Cheers LG
