In the book, the agent said Blackjack Survey Voice was described to them as something that could be used in real time but he said "...that is realistically impossible with the speed of the game, especially since you have to input all the cards of all players at the table for the program to get an accurate count...".

Also he described the difficulty of determining a player's bet size looking at the cameras in real time. It was too difficult to judge the height of the chip stack or whether different chip denominations were used. On a video review he was able to see the dealer spreading the chips on a payout or placing the player's chips to the dealer chip tray after a player loss to determine the player's bet size.
