For example, if the casino is making the expected profit, then the software might be in "fair mode"; if the casino had incurred a heavy loss due to variance, then the software might go to a "recovery" mode

(i.e. "player losing mode") and use the higher bets (of which most players will not place sufficient number to be statistically significant, so the risk of a valid complaint by a player is low for the casino) to get back to the level of the needed profit.
Here's how I think we can see that there's a hole in your theory Janek. Remember, casinos sometimes have bigger than expected earnings due to exceptionally unlucky players. If the casinos only had a "fair mode" and a "suckout mode", then some months you'd see the tables perform as expected, and other months you'd see the casino with a really huge win of its own, but never months where the casino's win is smaller than usual (or a net loss).
But, look at the results of audited casinos, and you'll see that the payout percentages have a fairly normal distribution.
This has nothin to do with theoretics...it has to do with years of EXPERIENCING the games in different environments...lets say it is 1 shoe...and the dealer deals out half the shoe..what are the chances of the same cards coming up on the next hand? Think about it...pretty much none to, but with a reshuffled deck each and every time, the odds of getting the same hand is raised and is not a fair system IMO ...(I am talkin AK,A10 etc...)
See, the reshuffling after every hand actually makes it even more important to stick with basic strategy.
If you're playing a live game, there is always the possibility that something will get out of whack as you progress through the shoe. More high cards, more low cards, whatever. This is what card counting is based on. Also, in rarer circumstances, you might not even get the shoe thoroughly reshuffled in between shoes, meaning that a slug of high or low cards from previously might still exist in the
next shoe.
These don't happen with an RNG that shuffles everyhand, because the computer doesn't have to worry about the mechanics of the shuffling procedure. Every hand is like playing a brand new shoe, and all basic strategy is written for a shoe played "off the top" after a fresh shuffle.
But for some reason many of you still believe it is on the up and up and many believe playing perfectly will result in the same thing as real blackjack...and this is where you are very wrong...it is not REAL blackjack...it is a PROGRAM! One cannot beat even in a short run what one cannot have a fair chance at. Online black jack has been set to where it isno longer fair to a player even in short periods of play..
I don't understand why people will still play a game if they think it's rigged (not picking on you specifically silc, as you say, others have expressed feelings similar to yours)
