Labouchere Split-Line vs. Flat 1-Unit Baseline — 9-Hand Dragon Streak Shoe under 5% Banker Commission (75-Hand Stress Test)
In head-to-head trial S228-0 across 75 deals (5% Comm Streak, 1.0579% edge), Labouchere records a -47u peak survival-window and 14.24% ruin probability on a 80-unit stack, whereas Flat Betting logs a -19u trough and 4.80% ruin under the 60-unit limit.
