Ok here's an idea:
Bet 5 DS 1 unit and raise on the following schedule:
If we lose the first level play the 2nd and 3rd levels for 2 wins in a row. If we lose on the 3rd level we create a bank of 70 units and start over at level one but use the following recovery betting units schedule:
Since the bet selection hits so often we should be able to clear banks relatively easily?
I think I can combine this with a 5 coup session and a random.org selection of the open DS so that after every 5 coups we randomize our selection...
