So this guy is saying that he has a super edge just because he decides bet size and modifies basic strategy according to the exact composition of the remaining cards.

This calculator does what this guy claims he can do. Is this edge that much more super than normal card counting with simple basic strategy modifiations (according to the true count)? Is it worth all this mental harshness to attain this extra edge? Can this guy calculate the exact composition and also have in mind the best decision that each composition suggests? I think it is more probable that he is simply lying.
Beware of the above calculator. Someone told me that it calculates wrongly the edge of the player. Can someone confirm whether it gives the correct decision tables though?
OK I see what the calculation is doing. It is based on a fixed probability of drawing a card based upon initial shoe composition. This is a quote from the site in the link -
"The computation is an approximation based on the assumpation that the actual probability distribution of remaining cards is fixed during the following game. All results are shown depending on the dealer's up card and in total."
In other words effects of removal are not included in the computation. For example the same calculation is done for 1 full deck, 2 full decks, 3 full decks, ......, any number of full decks. Likewise the same calculation would be done for 1 five removed from a single deck and 2 fives removed from a double deck. This is basically an inifinite shoe computation. I think the overall EV for S17, NDAS, no resplit infinite full shoe is about -.69% as compared to the web program's -.77%, so it's close but still not right.
If you want something that uses all of the information to get exact values, check out my programs. The only values that aren't necessarily optimal are split values but they are still exact calculations and accurate approximations of optimal. In order to compute splits in a reasonable amount of time I use a fixed strategy algorithm. In my optimal comp dependent program for split EVs I have 2 options: 1) use optimal strategy of non-split hands and apply it post-split and 2) use optimal strategy on the first hand of a split and apply it to all subsequent split hands. In computing splits in my total dependent program, the hard and soft standing numbers are fixed. For example when 8-8 v 10 is split the hard standing number = 17 and soft standing number is 19. This is basic strategy and the present version uses basic strategy for overall computations. You can manually change the hard/soft standing strategies for individual hands, though, and you will find that you are slightly better off standing on hard 16 after splitting 8-8 v 10 for any number of decks up to program's limit of 8. The comp dependent program's deck range is 1 to 41,297,762 so a virtual infinite deck could be created by inputting a very large number of decks. For a very large number of decks, the removal of a relatively small number of cards has virtually no effect on calculated values and optimal comp dependent strategy becomes the same as total dependent strategy. Infinite deck strategy for 8-8 v 10 is to hit to hard 17/soft 19 after splitting regardless of whether the computation is optimal or total dependent.
As for your question as to whether exact composition could realistically be used at the table, "No way Josê.
