Hi Dingoboy - from my understanding the increasing of the divisor acts as a method of protecting your bank, so that once the divisor starts to increases the bets do not.

that is - my divisor is 9, after a run of 9 outs my bet is up to (for example) $50 & will stay there until i strike a winner or lose my bank (something i never come close to while using this plan).

As to your strike rate of 40-45%, this probably isn’t the important figure – what is your average dividend? If it is below say $3.50 - $3.00 this plan may not be your best bet.
