STAGE 2 BANKROLL MATRIX · D'ALEMBERT · 20U / 1-SHOE
D'Alembert Pyramid — 20-Unit Bankroll & 1-Shoe (72-Hand) Risk-of-Ruin Matrix
Case M276-0 maps the commission-adjusted D'Alembert Pyramid (+1 on loss / -1 on win) across a 20-unit bankroll and a 72-hand (1-shoe) window, where a 40-unit table ceiling and 10-unit stop-loss produce a 39.47% ruin rate while benchmarks an average stake absorption-curve of 1.16x and 1.08u ($27) 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.
