I read from "You've Got Heat" that casinos uses BJ Survey Voice to analysis the skills of advantage players. BJSV request the users recite by voice every card value seen and the bet amount made by the player. Betting like a progression player does confuse the computer tacking software but it also reduces your SCORE. Does plays like hitting a hard 17 vs A or hard 17 vs 8 at negative counts confuse computer tracking software? I learned that making stupid plays the skill evaluation of any play under suspicious of counting.
