what's the major playing index change when switching from S17 to H17

If the rest of the game conditions are similar, 2D, double after split and penetration 0.7, what would be the major playing index differences? I suspect that I should hit more when facing dealer's 6, if I have 12. Currently I hit if the RC is less than -2, using zen. But when I use CVIndex, I got the opposite. It suggest to hit when RC is less than -4. Any comments?

The only major changes are hands against dealer 6 & A. zg

Here are what I got from CVindex
S17
12 vs 6 Hit < 0
11 vs A DD > 1

H17
12 vs 6 Hit < -4
11 vs A DD > -2

It appears that I should hit less when I have 12 vs 6 but double more when I have 11 vs A. Do you agree with the direction of the changes?

Yes, those make sense.
The dealer 6 and the dealer Ace are both more likely to bust in H17.
