Casino Verite: Problem Generating/Using Index Numbers

I posted this already over on QFIT, but thought more eyes might see it here:

I'm having a problem simulating a playing strategy that I generated using CVIndex, and I was hoping someone could help me. Whenever I run a simulation with my playing strategy I designed specifically for my parameters, the resulting win rate is much lower than just using Wong's Hi-Lo numbers.

Here's what I did:

First I did a "control" simulation with the following parameters:
- 75% pen
- 400M hands
- S17, no LS
- Wong's Basic Hi-Lo strategy with Illustrious 18 indexes
- Bet spread 1-12 (1 unit at TC<2, 2 units at TC 2, 4 units at TC 3, 6 units at TC 4, 10 units at TC 5, and 12 units at TC 6+).
- unit size $10

This resulted in $13.83 win rate.

I then plugged the same parameters into CVIndex and generated "Big 63" indexes.

Then I created a new playing strategy using the indexes I generated. The result was a win rate of $1.54. It didn't seem to make sense that the numbers would have reduced the win rate (especially by that much).

Here's how I made the playing strategy:

Under the Playing tab, I clicked "Define/Edit Strategies", then "Create New Strategy".

Under the Type tab, I clicked "Advanced", checked "Double down after split" and "Multiple Deck", and unchecked "Dealer hits soft 17" and "European".

I left the Counts, Insure, and Groups tabs untouched.

Under the Tables tab, I clicked each of the red boxes under "Soft 17, Mult." and entered all of my indexes.

Then when I tried to run a simulation, I loaded my strategy chart as the "Primary Strategy" under the "Playing" tab, and the result was the $1.50 win rate.

I've checked all the parameters to make sure there wasn't something else wrong with my simulation. At one point I ran the sim that was giving me the low win rate, stopped the sim and changed the Playing Strategy back to Basic Hi-Lo, and didn't touch any of the other parameters. It gave the right output ($17/hr or so). So there must be something wrong with the strategy chart I've generated, but I've double checked it a bunch of times, and I didn't make any errors entering the numbers. The index numbers themselves appear to be good, as they closely mirror the Illustrious 18, aside from a few minor differences (such as standing on 13 vs 2 at 0 instead of -1).

If anyone has any suggestions about why these new indexes don't seem to work, I would really appreciate it.

Thanks.

There are so many ways something could be wrong..... Qfit will probably ask you to send him the file so he can see what you did but I would suggest you go back to your "New Strategy" and make sure you have everything set correctly.

You didn't mention above how you set the TC divisor.

and as I read your above post again....

you created a big 63 set of indices and then used those for your new strategy.... but those indices were generated for the original strategy. What did you modify in the new one that is differnet from the old one?

I am not exactly sure what you did but somethings sounds like your working it out backwards.... try starting over from scratch.

Set up a new strategy using Basic as your new strategy and then go to the define new strategy section and under the "counts" tab enter the card tags you want to use.

Then set up the playing conditions and rules...

now go and run your indices in quick and dirty mode just to get some fast results.

See if the indices match your original Big 63 set.... most probably not....

Good luck
