Martingale Doubling — 20-Unit Bankroll & 1-Shoe (72-Hand) Risk-of-Ruin Matrix
Case M101-0 evaluates the combinatorial Martingale Doubling (1-2-4-8-16-32-64) across a 20-unit bankroll and a 72-hand (1-shoe) window, where a 40-unit table ceiling and 10-unit stop-loss produce a 74.90% ruin rate while models an average stake trajectory of 1.51x and 1.64u ($41) in theoretical house-edge toll. 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.
