I underatand that it is a system and the system has rules that need to be followed.
But has anyone tried applying this system to the chance game of roulette?
Either reds and blacks or columns or whatever.
Those who swear by systems need not have huge databases full of race results.Just a leisurely day at the casino,leave your wallet at home,wth pen and paper.
Then if you make profit on paper you have got a useful system.If not,you've got a system which will keep you amused,but ain't gonna help you give up your day job.
