How fast does one really have to be when counting down decks before one is ready for the casino. Another member on this forum told me 20 seconds, ten times in a row, no mistakes. Most other sources have told me twenty five to thirty seconds, without any reference to number of times in a row or mistakes. To be sure, it's a good rule of thumb to consistently try to get faster and more accurate, regardless of your current speed. I just need to know when I can be ready to hit the casinos. Right now I'm at 22-23 seconds with the occasional 21 or 20.
