On the lower prices it probably would equate to that. But anything over around the 6/1 mark you can expect to lay at 15-30% over the TAB odds. Sometimes you get lucky on the 10/1's and can lay at around the same price. But generally, the lower the odds, the lower the percentage you have to offer over the TAB prices. I reckon there's two ways to build a profitable laying system. Method 1: focus on horses likely to be overbet by the general public, ie. placed last start, barrier 1-8, last start 7 days ago. Mehtod 2: Find a horse that has little chance of winning but for some reason is a low price. This is mainly what I've tried to do using price's ratings,eg. rated 6+ max sp 6.0 This is the area I'm weak on because I have very little knowledge of reading a horse's form and assessing it's chances.

How does the system run if you restrict the sp to 5/1 and under? I don't think -21% would be enough for the $2 to $11 range, you'd probably just break even laying those or you might make a small profit but probably wouldn't be worth the effort. Hi Daniel, sorry, I should have made myself a bit clearer... The "POT" I was referring to was the POT if you were backing the selections... Therefore, you need to take an immediate 5% if you were laying them on betfair, and then a few more % for better prices.... Without having tried it seriously, I'd reckon that a -31% POT on the "back" side might equate to about a 15% Profit if you were laying them... ?????? Cheers, Chris.
