I had to pause when reading "Professional Blackjack" (P. 220) when Wong indicated the Dubner count original index numbers from the second edition of "Beat the Dealer" if cut in half would better coincide with his index numbers. I had to pause because Peter Griffin (P. 98 "Theory of Blackjack") stated he knew for a fact that the Dubner index of .1 for 16 vs 7 was in reality .2. Here are three top people in the field and none of them agree and the margin appears wide.
Reviewing Griffin-1 in "The Theory of Gambling and Statistical Logic" by Epstein I notice that Griffin has not provided index numbers for 16 vs 7 or 16 vs 8. Griffin-3 (a.k.a. UAPC) provides index numbers for 16 vs 7 and 16 vs 8 of 18 and 20 respectively. Numbers that are seldom if ever reached.
One could purchase simulation software to get different index numbers but again it falls back on the algorythm. Not an important issus but something I am perplexed about. Any comments would be appreciated.
