I've been looking for a formula to calculate the EV for the D'Alembert Progression. I haven't been able to find anything, I've checked around and all I get is that the progression makes it too difficult to calculate. I've found formulas for the Martingale, but nothing for a D'alembert. Since we already know the D'alembert wins on a 50/50 game, I was hoping to find a formula to calculate the EV for it.
P.S. This came up in another thread. But, I never did find a formula for the D'Alembert.

It's simple. If you have an edge, the d'Alem is
wonderful. If you don't, it sucks. Just like every
other progression.

The D'Alembert is the "Edge" on a 50/50, Bob. But, I was looking for a mathematical formula for calculating the EV for the D'alembert, do you have one?

That's the possible outcomes for 4 in a row. That's 64 trials, 32 wins/32 losses. How's the D'Alembert doing there, is it winning? How about the Marty, breaking about even? That's the "proof" that the D'Alembert beat a 50/50 game. You can do that for how ever many trials you want. D'Alembert still wins, Marty still breaks even. Or you can look at another thread where someone did a simulation for a million trials.
But, again, I'm just looking for a mathematical formula for the EV on the D'alembert. Not even sure if one exists at this point.

That's an awesome proof.
Your EV is simply player's edge multiplied by the total $ in action.

Really, that simple, huh? Well, here's the proof for the martingale breaking even.
E[P]=∑k=1Napk+(−SN)(1−p)N=a[1−(1−p)N−(1−p)N(2N−1)]=a[1−(2(1−p))N]
Probably, pretty close to what you're talking about, but, again I was looking for a mathematical formula, not misguided sarcasm.

What's your proof? 2+2=4 and my daddy told me so, so it's true?

This one's got some potential. Spunky, I like that.
Martingale is break-even because it is being applied to a game with 0% house edge. It is not the system that determines the EV, it's the HE that determines the EV. Some systems will just experience more variance than others (ie: a 1-10-100-1000-10000 player will feel some variance, while the 1-1-1-1-1-1 bettor will feel very little variance).
