STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 20U / 3-SHOE
Grand Martingale (2x+1) — 20-Unit Bankroll & 3-Shoe (216-Hand) Risk-of-Ruin Matrix
Sequential profile M127-0 evaluates Grand Martingale (2x+1) over a 3-shoe (216-hand) horizon with 20 units: bankroll-constrained escalation (1-3-7-15-31-63-127, 7 steps) interacts with the 60-unit limit to models a 94.80% ruin rate and a drawdown-weighted threshold of 1.67x. 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.
