To make this system humm is to reduce the divisor by the price rather than the odds so as to give oneself an edge on when one has a small level stakes loss potential.
At the end of the day one has to is to pick a bunch of winners paying $3.00+

Low divs are the No.1 killer ,one will find this out by punting on the Dogs & especially Trots, its mind numbing how many short priced Favs get up over 100 bets paying next to nothing , you will be lucky to break even.
