Top 50 indices for H17 Hilo?

I'll admit: I have very little idea how to use CVData (and I think my trial version is long-expired anyway!). What I have here is a list of the 50 indices that I use for Hilo, and I was wondering if anyone can possibly see if these are indeed the most valuable indices for the following conditions, and if so, what percentage of the value of the full indices these would represent:

6D H17 DAS RSA LS Wong out @ -2TC

Any suggestions for replacements, insertions, etc. would be very appreciated. I know there's a relatively easy way to figure this out on my own, and if anyone feels like pointing me in the right direction, that would be helpful, too. The -1 indices are there in case wonging out at -2 is inconvenient or for situations where the conditions are good and the count has only slightly dipped below -1 during the play of the hand. Anyway...

Code:
Ins   3
16vA  3
16vT  0
16v9  4
15vA  5
15vT  4
13v2 -1
12v4  0
12v3  1
12v2  3
11vA -1
10vA  3
10vT  4
9v7   3
9v3  -1
9v2   1
8v6   2
8v5   4
8v4   6
A8v6  0
A8v5  1
A8v4  3
A8v3  5
A7v2  0
A6v2  1
A5v3  4
A3v4  2
A2v5  0
A2v4  3
TTv6  4
TTv5  5
TTv4  6
99vA  2
99v7  3
77v8  4
44v4  3
33v8  5
33v2  0
22v8  5

Surrender:

17vA <1
16v9 -1 
16v8  4
15vA -1
15vT  0
15v9  2
15v8  7
14vA  4
14vT  3
14v9  6
13vT  8

Looks Good

While off the top of my head not sure on the indice numbers for hi lo.:joker::whip: They look fine. Do you have all the catch 22 fab 4? If you add any you will not necessarily get any more value.

Actually, this is a very difficult problem.
It's kind of a fun one though. What I did was take Griffin's playing EOR data, but only for the I-18 hands that a modern Wonging player would be expected to have money on. E.g., 16 vs. 10 is not a decision, if you have more than a minimum bet down, you stand. Same for 11 vs A, 9 vs 2, etc. Multiply that by the frequency of seeing each hand (15 vs. 10 becomes the most common), and again by a finagling factor that approximates the frequency that the hand becomes controversial (again, 15 vs. 10 is not an issue in marginally playable counts, you hit.) and another finagling factor that approximates the amount of money you'll have on the table when you need to make this decision.

The playing EOR change considerably, and the ace goes from being a low to a high card in this circumstance. Zen ends up being a really good count for playing decisions at high counts, better than an ace-neutral count. It can surely be improved though.

For my next project I'm going to open a beer, climb on the elephant, and get the EOR for the late surrender plays and see how it changes for those desirable games.

I can't find the site but I've seen the percentage gain in thousandths somewhere for a 1-12 spread 6 or 4 deck game. I think the numbers are schlesingers. 14v10 surrender is valuable, one of the top deviations.

To get an approximately correct idea, which I imagine will more than suffice for your purposes
- simply consult the data in P. Griffin's The Theory of Blackjack, 6th ed. There are two charts
- one for shoe games and the other for single deck. Early editions of TToBJ only had a single deck chart.

These tables give the value of each Basic Departure Index in thousandths of a percentage point.

Insurance is the most important, followed by 16 vs. Ten.
All of the pair splits and doubles are without much value.
