Auto shuffler scam

I play blackjack at an Indian casino. Whenever there is a full table of card counters using basic multiple deck strategy it seems that there is an unbelievable amount of hands that the dealers up card is either a 3.4,5,or 6 and the dealer will pull to 21 at a greater than 70% rate ! Is it possible that every card is being read and therefore stacked to the dealer's advantage whenever there is a full table. The casino could mark all the cards as they do the aces and tens to check the dealer down card for blackjack. Has anyone else experienced this on a consistent basis or is it just paranoid coincidence experienced by our team ? It always happens when the automatic shuffler is used . Whenever the auto shuffler is broken and a hand shuffle is used the phenonemon disappears. Has anyone else out there experienced the same frustration with auto shufflers ?

The single-deck shuffle machines used in carnival games can identify cards (they can be used to sort a deck).

ASMs, AFAIK, canot identify cards and so cannot arrange the cards in any way. Evem if they could, how would they arrange the cards so that the dealer wins (with changing factors such as no. of hands at the table, player hit/stand decisions, etc) ?

If you really could control the shuffle (can be done using gaffed cards or extremely, unusually skilled dealers), one way to hurt counters is to clump high and low cards together - so when the count is rising and you bet up, you're betting into garbage (more low cards). Then all the high cards come out together, with many pushes. However, this is noticable - the one case I know where this was done for sure counts were peaking and bottoming at a rate a blind man would have noticed.

I too have a "gut feeling" about unusual results with ASMs, but as there is zero evidence to support this I just ignore it.

Because they are a team and don't want a slow game.
