STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 50U / 5-SHOE
Grand Martingale (2x+1) — 50-Unit Bankroll & 5-Shoe (360-Hand) Risk-of-Ruin Matrix
When a 50-unit stack enters a 5-shoe (360-hand) session using Grand Martingale (2x+1), commission-adjusted model M135-0 verifies 965u in cumulative action and a 94.80% barrier-absorption probability before the 80-unit table maximum truncates the absorbing-barrier distribution. 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.
