STAGE 2 STRESS TEST · D'ALEMBERT VS FLAT BETTING
D'Alembert Pyramid vs. Flat 1-Unit Baseline — Two-Shoe Strict Alternation on Even-Money Player Wagers (140-Hand Stress Test)
In head-to-head trial S208-0 across 140 deals (Player 1:1 Chop, 1.2351% edge), D'Alembert records a -21u peak footprint and 18.31% ruin probability on a 95-unit stack, whereas Flat Betting logs a -11u trough and 7.64% ruin under the 70-unit limit. Because every 8-deck coup is statistically independent under Even-Money Player Side (1.235% edge) (1.2351% edge), progression rules alter drawdown speed and table-cap collisions without changing per-hand expectation.
