i would suggest you start live testing onion, as if ive only learnt one thing about system betting its that until you can get them churning out a profit that you can then withdraw & magically turn into goods or services you may find useful, said systems arnt worth the proverbial paper they are printed on

sound like we have a similar approach in some respects, i also self generate a set of ratings which are then filtered, & back the top rater, on average betting 2 races out of 8, but operating 7 days a week on the 3-4 main meets

can have a shocking run of outs (going thru one at the minute) but to date always bounces back & betting live has been generating solid returns for sometime, not going to fund my retirement anytime soon tho

the question then becomes 'when do i up the stakes?', in my case when ive turned the starting $1000 into $5000, maybe then...maybe $10000 would be safer
