I have tried many such progression systems. You get on a roll and win and win and win. I started with a couple hundred and worked it up to over $7000 in about 2 years. Then all of of sudden, it would not work any more - all the tweaking in the world did not help.
This is the way it works:
1) You start winning, and you keep winning
2) You lose a few and start tweaking your system
3) Nothing works and you begin losing and losing; searching for that special
magic you discovered and its no where to be found
If you don't believe me, buy the blackjack program CVBJ (
www.qfit.com)
You can program almost every conceivable BJ option (decks, rules, penetration, players, etc.)
Practice your game on this program - keep track of your winning sessions - (CVBJ will do it for you) - I have gone over 40 winning sessions in a row - then all of a sudden you will have a catastrphic session you cannot recover from.
Progressions are like heroin or meth - you'll get high as kite initially and think you're on top of the world, then it will destroy you!
