I'm a little confused reading online on UBZ2. Some give the IRC for Double Deck at -6 and some some give -4. So, which one is right? Pivot point is at which count?
If anyone has the index numbers, please also provide.
Posting is no longer allowed but there is a sticky post at the top of the Card counting page with the complete Open Sourced UBZ System with index numbers for simple up to complex versions of the system.
