STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 200U / 2-SHOE
Grand Martingale (2x+1) — 200-Unit Bankroll & 2-Shoe (144-Hand) Risk-of-Ruin Matrix
Across 144 eight-deck hands (2 shoes), asymmetric simulation M144-0 for Grand Martingale (2x+1) on a 200-unit bankroll evaluates a 18.68% risk-of-ruin figure, models 26 ceiling-collision events against the 50-unit cap and a 39.66% mid-corridor finish rate. Every 8-deck hand remains statistically independent (45.86% Banker, 44.62% Player, 9.52% Tie), meaning progression sizing reshapes session variance without altering the house edge.
