I'm totally underwhelmed.
This is just another computer program, although possibly a decent one, for evaluating suspected counters, requiring the laborious manual entry of data. How often do you think a casino is going to go to that much trouble?
A much more serious threat is an employee with the skill to evaluate your play in real time, and whom management has given adequate time free from other duties to do so. Once you're flagged by such means, and continue to spend enough time at the table for a complete evaluation, you're dead meat. The details of how the casino does that evaluation aren't terribly important.
Any casino that relies on a crutch like "Blackjack Approximator," as a substitute for training personnel well and giving them adequate time to do their job, is doing APs a favor.
My favorite quote:
"MR: That’s pretty impressive. What sort of count is built into this thing?
VL: That’s a secret."
Shouldn't take long to figure that one out.
But thanks, Finn Dog!
