I belive I answsered this question from another person earlier in this long, long thread whic his now 16 or 17 pages. I woudl ask that you please look through the threads first before asking questions since I may have answered that questoins previously.

With that being said, I will include a chart wiht betting efficinecy fo KO and for KO + (1/2)*(45m79c) below.

Note that this chart is for the S17, DAS, LS game. I am not sure what game Blackard Card Counting efficency refers to . I got the EoR for ths S17, DAS, LS from BJA 3rd edition by Don Schlesinger.

So looking down the column labeled X1, KO count and looking at the row CC = CORREL(Y-array, X-array) you will see KO's CC with betting EoR are 96.51% which just happens to be the exact CC for betting that HL has for the S17, DAS, LS game. Aid if you look at column X4 which is KO + (1/2)*(45m79c) you will see CC = 99.57%. A similar analysis replacing 45m79c with 5m7c shows that KO + (1/2)*(5m7c) has a betting efficiency of 99.0%.
