STAGE 2 STRESS TEST · D'ALEMBERT VS FLAT BETTING

D'Alembert Pyramid vs. Flat 1-Unit Baseline — Single-Alternating Chop under 5% Banker Commission (72-Hand Stress Test)

Evaluating D'Alembert vs Flat Betting in scenario S199-0 (72 hands, 60u stack, 50u table limit) documents how 7 tie stalls (9.52%) and a 2-coup run shape eight-deck envelope, yielding 15.34% vs 5.84% ruin. Because every 8-deck coup is statistically independent under 5% Banker Commission (0.95:1) (1.0579% edge), progression rules alter drawdown speed and table-cap collisions without changing per-hand expectation.
