iwantmore IMO you need to STOP what you are doing now and re evaluate things.
I can't see how this 'lay the draw' plan can work for you because I see no evidence that you have detailed knowledge of these teams. It is possible to have a statistical approach without having detailed knowledge of individual teams but I can't see any evidence of that either.
You won't gain any EV or advantage laying a draw unless you know that the odds to be wrong. And you can't work that out unless you have a statistical method of pricing up the win/draw/loss for the game. To see what I mean you need a book like this:
[ame=http://www.amazon.co.uk/Fixed-Odds-Sports-Betting-Statistical/dp/1843440199/ref=sr_1_1?ie=UTF8&s=books&qid=1271150181&sr=1-1]Fixed Odds Sports Betting: Statistical Forecasting and Risk Management: Amazon.co.uk: Joseph Buchdahl: Books[/ame]
I actually haven't got this book but I have the Silver coloured one by Kevin Pullein as it's solely football based. If you read it you would understand that you can't have a blanket apporach game after game unless the odds continue to be incorrect. Which is unlikely. And I personally doubt your knowledge of Terek Gonzi for example is better than all the other Betfair clients.
Don't give up this diary but I think you need to refocus. How about dry running for a bit after reading up more? Also put up a budget of whatever amount and have a staking plan. Stake 1 point for a 5/1 shot and five for an even or odds on bet.
If you look at someone who is successful like Eoin he is doing a bunch of different bets and strategies. Also he likes his stats. But if you look at his betting patterns it is generally on things he has a good knowledge of too. It's much harder betting foreign leagues unless you have detailed information. Like I just read today German and Austrain refs often don't add much time at half time injury time. Little things like this can have a big impact on in running odds.
Maybe you have a team in which you can specialise? Some of the biggest profits are to be found backing teams in Div 1 and Div 2. Maybe you can find a gem there?
If it's any consolation I have a bunch of punting horror stories. I once lost over £250 on tennis without a ball being served by backing and laying accross two markets for what I thought was an arb only for a player substitution to render one side useless. The trick is to learn from the mistakes and not to repeat them.
