Default Hit or stay on 16

What is the mathematical statistic of hitting 16 against 7 through Ace?
What percent will you win or push by hitting it?

What percent will you win or push by not hitting it?

Can anyone direct me to a site which publishes such stats?

You push 0% by not hitting. I hope that helps.

Its not even close. Just trust correct basic strategy, which we are guessing you do not know. zg

Not the %, but more importantly the EV.

Just follow the basic strategy charts. What makes the difference what the odds are of the dealer busting? it's all calculated in basic strat. If you stand on a 16, you're not betting that's enough to beat the dealer, you're betting the dealer will bust. Your odds of winning by standing on a 16 vs. a dealers 7, are the exact same odds of winning by standing on an 11 (5-6). You can't win unless the dealer bust.
Pushing is impossible by standing on 16

Also the reason you sometimes would hit on a 16 vs dealer 10 is so you will lose less, not to win.

I am sorry but this is not true, the odds are different

16 vs 6
player's probabilities for standing
p_-1 = 0.589511449401
p_0 = 0
p_+1 = 0.410488550599
p_+1.5 = 0
EV for standing= -0.179022898802 0.983844907343

***********************************************
11 vs 5
player's probabilities for standing
p_-1 = 0.566326835062
p_0 = 0
p_+1= 0.433673164938
p_+1.5 = 0
EV for standing= -0.132653670123 0.991162450763


Basic strategy takes into account all possible combinations of playerHand/dealerHand , bust rate of the dealer is mythical figure used by scam system promoters

I hope you realize that you did 11 and 16 v 5 and 6 respectively, not 7 as was the situation in question. Why didn't you site 11 and 16 against the same upcard?

I noticed that too, I think some people look way too deep for some kind of a quotion, or mathmatic formula to make something easy look complex. The dealer is either going to bust or not, that's why counters count, and understand the best times to do certain things. It doesn't matter if you have 4,7,9,12,or 16, you can't win if the dealer doesn't bust. There is a very long and complicated equation that explains why, and how gravity affects objects of all sizes, shapes, and weight. The bottom line is, if you throw a ball in the sky, it is going to drop.
