STAGE 2 STRESS TEST · FIBONACCI VS D'ALEMBERT
Fibonacci Negative Sequence vs. D'Alembert Pyramid — 11-Hand Banker Run under No-Commission Banker 6 Half-Pay (74-Hand Stress Test)
In head-to-head trial S343-0 across 74 deals (No-Comm Streak, 1.4579% edge), Fibonacci records a -54u peak envelope and 13.84% ruin probability on a 90-unit stack, whereas D'Alembert logs a -30u trough and 7.57% ruin under the 65-unit limit. Because every 8-deck coup is statistically independent under No-Commission Banker 6 (0.50:1 on 6) (1.4579% edge), progression rules alter drawdown speed and table-cap collisions without changing per-hand expectation.
