STAGE 2 STRESS TEST · FIBONACCI VS D'ALEMBERT
Fibonacci Negative Sequence vs. D'Alembert Pyramid — Three-Shoe 15% Tie Density on Even-Money Player Wagers (210-Hand Stress Test)
In head-to-head trial S350-0 across 210 deals (Player High-Tie, 1.2351% edge), Fibonacci records a -29u peak absorption-curve and 31.31% ruin probability on a 130-unit stack, whereas D'Alembert logs a -19u trough and 13.98% ruin under the 85-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.
