Understandable. However,
They have these things today known as high speed computer chips. And along with two really, really good index generator applications known as SBA and CVDATA, you can produce your very own RA indices that are, in fact, superior to Bryce's.
There's not a great deal of differences, but they're there. You'll find that most of the high stakes BJ players use their own indices. and more specifically, tailored to their specific games.
For clarification's sake, Blackjack for Blood, both the betting ramps, and Advanced Omega II with an ace side count, were targeted for Single and Double Deck. I've been an AOII user since 1992. And if anyone picked up the book today, learned this incredible count system, with the published indices, they would be very happy, and not notice a great deal of difference for moderate stakes.
It just so happens, that A6 vs 2 falls into that category of very high risk play variations, that high stakes players would just as soon avoid, or should I say, should avoid, at the published index of +2. The same type of effect is present with 10 vs 10. The published index is +9, and the correct RA indice is +13.
Hope this helps
