Hi Ellis Thanks for your extensive reply, yes I am referring to MDB+ in my email. New Zealand has 5 casino's, the one in Auckland was set up by Harrah's originally. All of the casino's are quite small compared to Singapore and Macau where I have also played. Haven't made it to Vegas yet. The bac tables here have different card preparation depending on the table minimum. The $10 minimum tables use a continuous shuffle machine, and the cards are changed occasionally due to wear, about twice a day I am told. The player does not touch the cards at these tables. It is an 8 deck shoe. The $25 tables are pre-shuffled cards, with 2 x eight decks in use alternately. One deck is shuffled by the machine while the other is in use, common procedure everywhere I think. Again the player does not touch the cards. The $50 and $100 tables are the same as the $25 tables but the players do touch the cards. This only prolongs the game but some players prefer this way to play. These cards are disposed of after each shoe and a new 8 deck pre-shuffled shoe is used. My records are based on the $25 tables, so they are pre-shuffled and then shuffled again after each shoe. I have observed (but not recorded) that similar results seem to apply to the $10 tables which gives me even more cause for optimism for MDB+. I have no data from $50 tables. Having read your reply I will stick with the 1,2,4 progression on the $25 tables best regards Paul
