Another Lay system

[El Stevo]

New poster to this site although been a regular reader for some time. I appologise if this has been done before (seen similar things) but I think it's a little different. Anyway, I tested a system last week and the results were:- 82 layed bets (all 10 unit stakes) 64 (79%) winning bets and a profit of 120 units. I am thinking of doing a paper trial but would would appreciated the experts view/ideas/input so that I can refine it before starting. Basically, what I will do is take the odds of one bookmaker (I have used Paddy Power) and if I can lay on betfair at odds of no more than 10% different to these odds I will do so. My thinking is that I will basically be acting as a bookmaker (and as they say, you never see a poor one). The odds that I lay at are obviously higher than a bookmaker but if I can limit the difference to no more than 10% I should get similar results to the bookmaker. They must have a margin of at last 10% built in to their odds and I will not have any of their overheads. A few things that I have would appreciate advise on:- 1. Does anybody know what a bookmaker generally has as a profit margin. I've assumed it to be at least 10% but if if I'm wrong maybe I need to change this criteria. 2. I've used Paddy Power because I think they generally offer reasonable odds but must still have that profit margin. Is that a fair assumption (I don't normally bet on horses - more of a football man). 3. I intend to limit the odds layed at to 7.00 simply because I don't want to get hit for a big one. However, the principle must be the same on long odds (although maybe the margin is different?) and therfore maybe I should not be using this restriction. Any advice very welcome and then I'll get it up and running. Cheers
