Contra D'Alembert Press — 50-Unit Bankroll & 2-Shoe (144-Hand) Risk-of-Ruin Matrix
Sequential profile M309-0 evaluates Contra D'Alembert Press over a 2-shoe (144-hand) horizon with 50 units: commission-adjusted escalation (+1 on win / -1 on loss, 10 steps) interacts with the 50-unit limit to models a 30.95% ruin rate and a absorbing-barrier envelope of 1.31x.
