I have a knock out question. I want to be sure I have the system right in the way it compares the initial running count (IRC) and key counts (point at which you multiply bet.) The book says with six deck you begin with an IRC or -20 and then a key count of -4. With eight decks it's -28 and -6. Why don't they simply start at -16 in a six deck shoe and -22 in an eight deck shoe. In both cases the key count would be zero. Am I missing something or not understanding? Similarly the two decks does not equal a zero key count. Any input? I just want to be certain that I understand what I'm supposed to be doing here.
