Hi Ellis, the cards come in one box and hand-shuffled on the tables in front of players before put in the deck for play. From what my friend told me, they have nothing to do with changing the randomness of the cards or have "orders" from anyone. For me, it doesn't matter. When I play, I just wait for a few hands to be dealt and choose the right system to start with it. And just keep on O/R count to locate the L/C along the way. If, it is not smooth or it is going agaist my ways, I will simply find another table. I do prefer to play with choppy shoes, because they are easy to beat with S40. But, if I cannot find a choppy shoe, I will choose the least streaky shoe I can find and deal with it, by using S40A.
