Jesus, I don't even know if I play that fast online.
(Haven't clocked it though)
But I was wondering this question when considering a +EV situation like a 2:1 blackjack promo (or 3:1 suited). If you were just going to sit down and play basic strategy, it would probably be best to find the game with the lowest innate edge, and play as fast as possible. but if you have the choice between an 8D game and a 2D game, would the extra shuffling (and slowness of pitch play) actually slow you down enough to where the 8D game became the best choice?
