i cant see it. can you explain little more simply.....
When you do this it takes about ten minutes (unless you're really unlucky - or really lucky)
Mathematically its hard but one way of looking at it:
The probability that you bust out (and stop being able to wager) is higher the bigger the bet you make. If you make a very small bet then because you make so many bets (your standard deviation goes as root number of hands) - then you are less likely to bust out. (OK the number of hands guarantee a loss rate but this is the other end of the risk/return)
If you double up on a big bet you have to decide what to do. Triming profits is a good thing (i.e take your $100) you just cant keep doubling up...only a loony would keep staking what he has just won.. until he bust.
It turns out you need to play about 30-50 hands to reduce the probability of busting but keep your work rate reasonable. The above system does this.
Its not a big effect but it adds a few more percentage points.
Key to all this is the bust out or trim profits effect - it adds a little bit of a funny in the maths (not vast amounts). So the idea of averages and statistical deviation (which assume linear effects) crumble a little.
This is not a system for getting rich. is does a couple of things:
1] gives you a few more percent given the right casino set up.
2] Means you play about 30 hands of BJ - this is usually enough for me

I stress this ONLY works for Party type setups where you can trim profits. Most casinos don't operate like this.
