With all due respect Bojack, it's not the act of counting that's hard while dealing. Rather it's the fact that there are so many distractions while doing it that require most of your concentration, that should you focus more on the counting, you risk making errors in dealing and not providing the customer as good of an experience thereby lowering tips or what not. You made one key point in your statement. "Concentrate less on the mundane" There is often little that's mundane when dealing as I know I continually face the unexpected, whether it's someone spilling a drink, people trying to raise bets while having already started to deal, etc etc. Personally I can scan a table and have the count in a second, count down a deck in under 25 seconds, achieve a perfect score on the iphone's card counting app, etc but nothing to me will test you like this. I know it probably can be done but I would love to see someone accurately maintain the count in an 8 deck shoe consistently while dealing professionally at a PLOPPY table
(It's more mundane when you have players who have played BJ many times before) I'm willing to bet that not even 10% of the AP's on here can do this. I think what you're looking for are AP's who can just glance at the table and automatically have the count without having to manually add it up in their head. The hardest aspect of counting for most AP's I would guess is doing an accurate TC division with under 1 deck remaining, say if you have 5/8 of a deck left with a RC of +7
To avoid being detected as a counter as you know, you need to be able to do this division instantly.
