G'Day Bhags, I agree that block plan this maybe better on the palpitations, but and I'm afraid I'm going to be a "party-pooper" again, the nitty gritty is this:

Work this plan for a while , then when there has been heaps of bets do the following exercise:

Add up the TOTAL AMOUNT bet, divide it by the TOTAL no. of bets to give you your AVERAGE bets size,

Now apply that amount ( hypothetically) to the total winners and see what your return is........

You will find that the POT at the level stakes (if any) is exactly the same as with the staking plan "GUARANTEED"
