thorns - no ratings method ever devised in the history of the world can level stake 5 horses a race regardless of price over virtually every race and make a profit. It's an unrealistic expectation. Don't look for that as your answer because you won't find it, anywhere. 79% strike rate in the top 5 is a very good strike rate, and given that the LOT is only 11% level staking all 5 of them (and I do mean ONLY, because backing 5 horses a race flat stake regardless of price is a fast way to the poor house, therefore 11% is a good result in that scenario), then it is highly likely that you can turn that into a sustainable POT, with sound betting practises. As always, the key is to look for value in the selections, not to flat stake regardless of price.

Good luck.
