Hi, Thanks for your reply. It's not martingale. It's the five point divisor plan I think it's called or money factory it's named.

It's add five to the divisor after 10 races where you have not made a profit on the series however the series can drag on where you still have not made a profit even after 20 bets however what I don't really know and is not explained in the book is if another 5 is added after a second set of 10 bets where a profit has not been achieved.

Can anyone clarify any further who may use this staking plan at all ie money factory 5 point divisor plan?
