I have read all I could find on how the current CSM's work. My conclusion was that the cards inserted back are shuffled and then placed at the back of the internal "shoe". I see no way that cards can appear in the next hand like advertised. The casino closest to me uses CSM's exclusively that holds 5 decks. I went there the other night to test my theory out by backcounting for a couple hours using the KO. What I found was very interesting. Being the cards are continuously added to an internal shoe, my thoughts were to count down 5 decks in full. I would find a table with 4-5 players that I thought would stay for 5 decks worth hands and start counting. I counted about 10 shoes that night at many different tables and my findings were encouraging. I noticed that in 7-8 of those shoes, the count would go up after about 2.5 decks and would hit the KC about 3/4 way into the 5 decks. Then, in the next hands, the 10's and Aces would appear in numbers! One hand during a high count, the 5 players and dealer got all tens and aces! These findings told me that there were some serious low and high clumping going on with all the shoes at around the same penetration depths and I don't think that was coincidental. I didn't play that night so I haven't tested out my findings yet but I will soon. I may be crazy but these CSM's may be beatable. Curious to hear responses.
