STAGE 2 BANKROLL MATRIX · D'ALEMBERT · 100U / 5-SHOE
D'Alembert Pyramid — 100-Unit Bankroll & 5-Shoe (360-Hand) Risk-of-Ruin Matrix
Case M290-0 charts the finite-shoe D'Alembert Pyramid (+1 on loss / -1 on win) across a 100-unit bankroll and a 360-hand (5-shoe) window, where a 80-unit table ceiling and 50-unit stop-loss produce a 39.47% ruin rate while computes an average stake cycle-span of 1.78x and 8.21u ($411) 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.
