I get that part, Geoff, but wasn't Paul Harris trying to determine how a spectator had tabled the deck? As we all know only too well by now, it wouldn't matter which end of the ace Mr. Harris turned over, but wouldn't it matter in which direction the spectator tabled the face-down deck? Why would the result be the same 10 times in a row? That would depend on how the spectator placed the deck, not on how Mr. Harris turned over the ace. Maybe a right-handed spectator, say, would always be inclined to table a deck with the top to the left -- the most natural movement. But I don't know, maybe I am misreading the description. Maybe that wasn't what Mr. Harris was trying to determine at all.
