STAGE 2 STRESS TEST · GRAND MARTINGALE VS FLAT BETTING
Grand Martingale (2x+1) vs. Flat 1-Unit Baseline — Ping-Pong Chop Shoe under No-Commission Banker 6 Half-Pay (70-Hand Stress Test)
Evaluating Grand Martingale vs Flat Betting in scenario S118-0 (70 hands, 65u stack, 50u table limit) charts how 7 tie stalls (9.55%) and a 2-coup run shape table-capped progression-curve, yielding 29.42% vs 5.93% ruin. Because every 8-deck coup is statistically independent under No-Commission Banker 6 (0.50:1 on 6) (1.4579% edge), progression rules alter drawdown speed and table-cap collisions without changing per-hand expectation.
