Good on ya! it's good when you're playing with "their" (or is it "our dough?,hee hee!) anyway I do something similar starting with 5 units betting (for the place) 1/5th of the bank never reducing, ruling off and sarting again if ever there is insufficient funds for the 5th/laST BET.
I take out the initial 5 units when the bank stands at 10 units,start again and let it roll till it reaches 100 units, then stop and start again, I've reached 100 units several times But as I say smaller bets just for fun!
