I came across this the other day, and imagine how dumb I felt. All this silly +/- numbers and division at the table was the wrong way to go. This guy has it made, no index plays to remember just need to have 52 things you can think of to correspond to the cards. Then put a sticker on them in your mind for each number of decks, and remove one every time the cards come out. Presto you now know what cards are coming next...

What a crock of shit lol if this was how it was done I think I would just stick to the slots lol
