STAGE 2 BANKROLL MATRIX · 2-1-2 MANHATTAN · 40U / 1-SHOE
2-1-2 Manhattan Progression — 40-Unit Bankroll & 1-Shoe (72-Hand) Risk-of-Ruin Matrix
Under step-indexed boundary rules in M406-0, pairing 2-1-2 Manhattan Progression with 40 units across 1 shoes (72 hands) and a 40-unit maximum maps a 18.60% stop-loss absorption rate, surviving at most 6 adverse steps before asymmetric survival-window 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.
