From Bootlegger's good work, here in the glossary...

'Fluctuations' "This word describes the ups and downs of your bankroll."

'Variance' "This can be determined by subtracting the expected value from each possible outcome in a game or hand, squaring the differences and multiplying each square by its probability of occurring and then summing the total of the product."

Sorry Boot; it's not your fault that I sure am no math nerd, but your description for variance flies way over my head.

There was some discussion here just recently on these, and as usual in BJ forums, much gnashing of teeth over them, which is why I began with Boot's word definitions, so we can all be on the same page.

Now I, for one would like to hear say, another (simpler?) explanation of variance; and without the use of math-nerd terms. (No disrespect, Boot!)

My own (uneducated) explanation is this: (For the moment, leaving out shuffle-tracking, sequence-remembering, ace-tracking and the like.)

Nobody can predict the flow of card sequences, which I don't think anyone will deny. So even if the count is in my favor, and I am but one of 6 players, (7 including the dealer) I must get 'lucky' to get what I want, when I want it, correct? Keep in mind the other 5 players are also expecting what they want, too. Some of us must miss out, obviously. Variance. (Makes me want to go back to baseball betting!)

Bottom line. Anybody else have an explanation/definition that I can almost understand?
