The interesting statistic from the people who contacted me was that the percentage of Blackjacks for the player overall was around 2.4%, almost exactly half the figure that it should be for 8 decks 4.7451% (32/416*128/415*2). What I think happens is that at the shuffle table the casino takes 16 of the aces and places them at the bottom. Then there is a single riffle in six sections followed by a cut, so that these 16 aces will not be in play in the new shoe. There will now be an average of 8 aces in the section that will be used in the new shoe, and not the average of 16 aces that would be expected for the (approximately) 208 cards that are used in an 8 deck game with the postilion inserted half way. I did a simulation for 8 decks with only 50% aces, and had a figure of -3.3% - no doubt you would be better than me at checking that!
