Dude, you need to learn to read between the lines. I didn't say you can beat a 6/5 game with 30% pen (you need at least 50% pen with a 1-12 spread min and the ability to jump bets at least 4-5X between rounds). What I did say is that you will get a higher frequency of favorable counts because it is a single deck. That doesn't mean they will be as profitable because a SD game is more volatile, now you see it, now you don't. In a shoe game, you have to bet, and bet, and bet, until once out of every 3 or 4 shoes a count develops. But when it does, it lasts.
