The divisor just keeps your bets down to reasonable levels,,,You will see that your bet is the same after 12 losers as it is after 6.You seem to be doing everything ok,,

It's just that odds dont matter.You are not looking for longer priced horses.

Say you get a winner after a losing run of ten,,look at your bank total,,then go back up the bank column ,, find a similar figure and resume betting from there.
