Crazy surrender

Hi!
I play frequently under these conditions:6D,S17,DAS,DA2,ENHC,ES10,No RSA(initial disadvantage aproximately -0.26,good,but terrible penetration,so it is a better option not to play).Instead of playing the right moves,I make the following changes( all come from Ian Andersen's "Burning The Tables"):
Always Surrender 16(except 8,8) vs 8; 16(except 8,8) vs 9;16 vs 10;8,8 vs 16;15 vs 9; 15 vs 10;14 vs 9;14 vs 10;7,7 vs 9;7,7 vs 10( with great pleasure).These changes(under my rules Surrender against A is not permitted) are known as Crazy Surrender.I want to ask is someone could tell me what disadvantage(in percentage) it brings(in comparison with the right decisions),it must be very small.Thanks in advance!

even in the HI-COUNT?

Catch a ten, catch an A, catch a 2, or3, double down and make some money!

Ill give some numbers at 0 counts so of course for minus counts the numbers get worse.
14vs9 at 0 = -7.1%! (meaning you only lose 42.9% by not surrendering vs 50% by surrendering)
15vs9= -2.8%
14vs10= -3.4%
16vs8= -4.7%
16vs9= basic sgy move at 0. but say 2 level count of -4 still only a -1.6%. Won't give up much on this one.

The cost of course will depend on your spread. If you use huge spread and bet tiny not only on minus counts but NEUTRAL counts as well the cost would be small.

Since you specifically limited your response to "high + counts" I would personally surrender. Infinite deck has splitting 8-8 vs 10 as a -.48 EV, which is .02 better than surrendering. But in a big + count, it is better to surrender. Trivial example is a game with 31 cards left, running count = +32. You have 8-8 and they are going to get 10's if split. Dealer has a 10 down giving him 20. Splitting has a -2.0 EV, while surrender still has a -.5... All you need is enough extra 10's to change that -.48 to <= -.50 and it is surrender time...

Now for the pure BS player, splitting is always the right answer of course..

Some of the surrender-plays you mention like 14 through 16 vs 10 and 16 v 9 are basic strategy but the others are indeed wrong and sometimes quite costly as you can see from AJs post.
Your idea is probably to play consistently regardless of the count (counter's BS) but this is not justified in a game with such bad penetration.You probably never get TCs where surrendering 14 vs 9 or 16 vs 8 is the right move.So I strongly advise you to remove these two plays from your list and even 15v9 is debatable (index +2).
