Mark, as the Lays are the 3rd choice of your "bet" selections I would be somewhat concerned.

Have you checked the 2230 races to see how the 3rd choice would have fared if you had eliminated those over $11 just as you are doing for the current lay method? In other words, is it possible those that started under $11.10 may have shown a profit?

Having said that, I am looking at a lay system based on prices, and as a matter of coincidence my selections in Sale race 5 and Gosford race 5 were also your selections - they were both beaten.
