Here are some interesting sims. Rules were 2D, DOA, DAS, S17, noLS, Catch 22 indices, 78% penetration. 5 billion hands. True Count estimated to nearest 1/2 deck and floored. Each system side counted aces for betting.

AO II: Flat Bet SCORE = $0.0333

1-2 SCORE = $22.94

1-4 SCORE = $71.06

1-8 SCORE = $117.29

Ace Neutral RPC: Flat Bet SCORE = $0.0365

1-2 SCORE = $23.91

1-4 SCORE = $74.48

1-8 SCORE = $123.43

Hi-OPT II: Flat Bet SCORE = $0.0442

1-2 SCORE = $24.11

1-4 SCORE = $73.43

1-8 SCORE = $120.56

I think the AO II did not do better becasue the other two counts have better insurance correlations. The IC's are AO II = 0.85, Ace Neutral RPC = 0.892, and HO II = 0.909. The Ace Neutral RPC had a bit better BE than the HO II, 0.984 vs 0.982. The AO II had the best BC of 0.989. PE's were: AO II = 0.671, Ace Neutral RPC = 0.657 and HOII = 0.668.

With more indices or changes in penetration or if single deck, things could shake out differently.
