STAGE 2 STRESS TEST · GRAND MARTINGALE VS FLAT BETTING
Grand Martingale (2x+1) vs. Flat 1-Unit Baseline — Three-Shoe Adverse 8-Run on Even-Money Player Wagers (216-Hand Stress Test)
Evaluating Grand Martingale vs Flat Betting in scenario S125-0 (216 hands, 140u stack, 90u table limit) quantifies how 20 tie stalls (9.26%) and a 8-coup run shape stochastic decay-rate, yielding 64.20% vs 8.20% ruin. Because every 8-deck coup is statistically independent under Even-Money Player Side (1.235% edge) (1.2351% edge), progression rules alter drawdown speed and table-cap collisions without changing per-hand expectation.
