imho while i agree that staking plans will not turn a losing method into a winner, i have been using the retirement plan for my win betting for a few years now & find it works well & gave me what i had previously been lacking with my punting - DISCIPLINE

so if one is to go down the staking plans route then my only suggestion would be to find something not too aggressive, boring almost, the retirement plan or variation of same fit that bill

party's suggestion of 1% of bank non reducing also works as well, in fact 0.5% is even better & what i use for my place betting
