I'm learning hi-lo to play 6D, and I'm wondering why I ever need to know the true count. Why is the RC-to-TC conversion necessary? Can't you just memorize the RC values that are important? For example, if you only want to play a game with a TC of 2, then instead can't you just watch the discard tray? You see one deck there, then the RC needs to be 10. You see 2 decks, then the RC must be 8, and so on.
