Labouchere Split-Line (1-2-3-4) — 500-Hand High-Limit Marathon (200u Bankroll) Survival & Ruin Proof
[LABS500] Stakes the sum of the first and last numbers on a 1-2-3-4 line; crosses both off on a win or appends the lost sum to the right end on a loss. Across 500-Hand High-Limit Marathon (200u Bankroll) (Six-shoe salon marathon exposing long-run house-edge drift against a 200-unit reserve), staking Labouchere on Player (1.2351% house edge) generates 1425.0 units of cumulative action, an expected mathematical cost of −17.60 units, ±60.62 units of standard deviation, and a 76.4% session survival rate (23.6% bankroll ruin risk).
