Modeling using CVData
Your strategy is within the simulation capabilities of Norm's excellent CVData program. You'll need to use an "Advanced" Betting Strategy for this.
Since your post did not describe the complete scheme, I made a few assumptions:
1. The "unit" used is $10.
2. For TC's of zero and below, you'll bet from $10 to $100 (1 to 10 units) using a Martingale approach: on any loss, you'll bet $10; after a win, you'll double your previous bet, capping at $100 (which you'll bet after winning an $80 bet in a non-positive TC).
3. If you bet $100 in a non-positive TC, your NEXT bet will be based on the TC, so if you win and the TC<+1, your next bet will be back to 1 unit. If the TC>0, then use rule 4.
4. For TC's of +1 and higher, you'll bet according to the count, with this schedule: $100 (10 units) at +1, $200 at +2, $400 at +3, $600 at +4, and $1000 (100 units) at +5 and higher.
Thus, overall you'll be spreading 1:100 in $10 units.
First, set up a simulation with the desired house rules, number of players, and playing strategy. Then go to the Betting tab and define a new strategy, basing it on the canned "Flat Bet" scheme. On the "Basic" screen uncheck the "Reset after shuffle" and "Running Count" boxes, and enter an Ending Index of 5. Then, enter the following schedule:
<=0 1 unit
+1 10 units
+2 20 units
+3 40 units
+4 60 units
+5 100 units
Now click the "Advanced" button. Locate the box at the intersection of the "Last Bet 1 unit/Won" row and the "<=0" column. Change the "1" there to a "2", and CVData will now create a new set of rows for a 2-unit bet. Now, locate the box at the intersection of the "Last Bet 2 units/Won" row and the "<=0" column, and enter a "4". Repeat to add an 8-unit row. Finally, locate the box at the intersection of the "Last Bet 8 units/Won" row and the "<=0" column and enter a "10".
Whew! Now you have a strategy that combines a partial Martingale at zero and negative TC's with a straight counting strategy at positive TC's.
I simmed a 6D, S17, DA2, DAS game for a heads-up HiLo counter with 75% pen, and got a win rate of $145.06 with a 1.513% Initial Bet Advantage.
Hope this helps!
