STAGE 2 BANKROLL MATRIX · 1-2-3-5 · 150U / 3-SHOE
1-2-3-5 Four-Step Ladder — 150-Unit Bankroll & 3-Shoe (216-Hand) Risk-of-Ruin Matrix
When a 150-unit stack enters a 3-shoe (216-hand) session using 1-2-3-5 Four-Step Ladder, absorbing-barrier model M217-0 calibrates 372u in cumulative action and a 14.89% barrier-absorption probability before the 60-unit table maximum truncates the variance-scaled boundary. 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.
