In CVBJ, I see this Color of Blackjack playing strategy is set up so that the index for 16v10 changes the deeper the player goes into the deck: 9, 12 ,15, 18, 21, 24

Its sort of like the REKO-I idea.

These numbers are a little different than the REKO-I numbers for 16v10: 2 6 10 14 18 22.

Why are the COB index numbers different than the REKO-I index numbers?
