STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 75U / 10-SHOE
Grand Martingale (2x+1) — 75-Unit Bankroll & 10-Shoe (720-Hand) Risk-of-Ruin Matrix
Under step-indexed boundary rules in M138-0, pairing Grand Martingale (2x+1) with 75 units across 10 shoes (720 hands) and a 100-unit maximum audits a 94.80% stop-loss absorption rate, surviving at most 7 adverse steps before asymmetric cycle-span truncation. 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.
