My experience with progressions was at Roulette.
Had a buddy "invent" a system years ago (turns out it was a martingale). He swore he and i would be rich. He took copious notes of our sessions for his book that he planned to write.
Here it is:
Find a half empty roulette table (don't want people waiting to sit down), buy-in....and wait for a repeat of three 'sames' on the "even-money" bets (three consecutive reds, blacks, even, or odds). Bet one unit. If you win, wait for three more 'sames' and go back to one unit. If you lose, keep doubling until you win.
The Croupier was cool. She knew what I was doing and let me dig my own grave. It was fine with her for me to sit out as long as I wanted to, as long as there wasn't anyone waiting to buy-in.
After 8 hours, I was up around $950. After 10 hours, I had lost my $950 and was another $1100 in the hole (13-straight reds tapped me out). I did get a free buffet for my efforts, however.
Stupidity has a high price tag.
