Take a look at handicap races today (Metro) Top 6 , 28 wins from 33 races. yes only 12% wins but look at some of the prices, 85% S/R (races) What I am suggesting is it's a handy place to start your calculations, combine that with 123 LS, and within 3.5 lengths of the winner LS, and see where you go?

I'm not saying that is the golden goose but let's just say it's interesting if you keep searching!
