a progression just means you change the size of your bet based on the previous result. What you describe is called a negative progression. Betting more after a win & less after a loss is a positive progression.

"You profit $20 with a strike rate of 50% on an even money game."

Find me an even money game. An no you don't. A progession won't ever be mathematically profitable by itself. The only progession that is actually useful is betting more the larger your advantage, and betting less or not at all when it's small.

"The figures 1.2 and .8 are just used as a quick example to show what I meant about betting more on a win than a loss."

Lol. You won't win as often as you lose in roulette, and that is the problem. Your wins will be worth slightly more than your losses, but you'll lose more often that win which will more than make up for it, and still give you an overall loser. Forget it, and forget trying to give mathematical examples. A progession cannot produce an advantage.

So many people have looked at this in MUCH more detail than you. It's been proven mathematically that progessions don't produce an advantage. This is fact. You are wrong. Don't wanna sound like an ********, but it's all true.
