comparison results (Zen, FELT, SIM52)
I'll run the same simulations using the Zen count defined by Arnold Snyder in the 2005 3'rd edition of Blackbelt In Blackjack. I'll reference the appendix and use the same 52 indices which my system uses, no Ten splits. All Zen indices will be multiplied by 4 in order to use "full decks remaining" true count calculations. Also, for some reason I have the double 10 vs. Ten index of +1 crossed out and replaced with +2 so I will use that instead (probably a more risk averse index). I can't find anything in Snyder's book about truncating, flooring, or rounding true counts so I will truncate. Remaining decks estimation accuracy will be quarter deck for all sims. Quarter deck accuracy results were actually slightly better than exact card accuracy in single deck. Rounding vs. truncating produced practically identical results as well.
I will also simulate Norm Wattenberger's FELT count found in Modern Blackjack at qfit.com. I'll use the Full versions found in the appendix for the appropriate rules and number of decks (different indices for single deck and multi-deck). I believe Norm forgot the 1 deck indices for doubling 8 vs. 4 and 9 vs. 7 so I'm going to use the 6 deck indices here. FELT floors true count calculations rather than truncate but I will use the same deck estimation accuracy as Zen (1/4 deck). Although FELT-F has more than 52 indices most of them are for pair splits which make little difference. Basically this is a Fairly Accurate Unbiased Level Two (FAULT) count comparison.
I'm going to name my system SIM52 because it's simple and there are 52 indices excluding Ten splits. SIM actually stands for something but I can't give away my twist just yet. I'm hesitant to call the count my own because like I said the tag values are well known (UBZen-II and it is not true counted). However I do feel that the implementation of the count is original and completely different. That's why I'm calling it my system but not my count. SIM52 uses the same indices for 1, 2, 6, or 8 decks with 10 differences for S17/ H17. To remember both sets just make the index a decimal (the integer would be for S17 and the decimal for H17) keeping the total at 52.
The impetus of all of this was when I made the mistake of customizing a system for one particular game. When that game ran out I was unable to play until I re-learned new indices. SIM52 is IMHO much easier than both Zen and FELT. If you can add, subtract, and multiply simple numbers you can easily manage SIM52, there is no deck estimation or true counting. SIM52 also has simple bet ramps which happen to be identical for 6 and 8 decks; these will be used for the results below.
As stated earlier, I will consider sharing the system with a respected authority if they are interested or wish to verify. Last I'm going to re-run everything with 5 Billion rounds!
