You misunderstood EVERYTHING ;)
I do not consider myself a progression winner (or progressionist). I said I just happened to win using progressions. Some will, most won't. The I graduated to forms of AP.
Sure, I might still use a progression here or there, but I don't fool myself into thinking I'll profit from it. Shorterm I might, longterm unlikely.
When I used them I knew what I was doing. I knew I was still playing a negative EV and therfore playing with fire. But then again I started off with nothing, and knew a progression can get some quick money together in a small amount of time. So I chose a progression that tends to have more wins than losses (which means larger losses). By being careful with it, I managed to build up a BR I could count off. I still used them (on a small scale) to boost my total BR, and it paid off. I have a large enough BR to live off AP play.
I am an AP and have been for a while. I actually learnt to count before using progressions. Still, progressions can be effective in getting quite a bit in a small amount of time (as long as nothing goes terribly). There was a risk, but since I started with nothing, I took it. I'm glad I did.
BTW, I actually count SP21. The deck pen is normally less than a deck off six. House edge is .2% worse than normal BJ, but I bet much higher on positive counts (of course they do happen less, but when they do they're very profitable). I get no heat. Imagine what you guys would do under the same conditions at BJ.
If they ever thought I was counting (seriously, who'd count SP21), they'd lower that deck penetration and see how I react.
They just see me as a kid with too much money, and happy to lighten that wallet.
