I have a theory that live games without shufflers have slightly more aces come on the board than would otherwise be dictated, because the winning hand has an ace more often than any other card, and usually the winning hand is scooped up last, putting it on the bottom of the deck before the shuffle.  And in standard "riffle, riffle, box, riffle, cut" shuffle, the bottom card ends up being somewhere between the 20th and 30th card a much higher percentage of the time than other locations, and in a 9 and 10 handed game, 4 or 5 of that 10-card range are the board cards.  Thus aces should come out more often.  [...]
