D'Alembert Arithmetic (+1u / -1u) — 50-Hand Sprint (20u Bankroll) Survival & Ruin Proof

[DALS50] Increases the wager by +1 unit after a loss and reduces the wager by −1 unit (minimum 1u) after a win. Across 50-Hand Sprint (20u Bankroll) (Fast 45-minute mini-baccarat or two-thirds shoe sprint with a compact 20-unit buy-in), staking D'Alembert on Player (1.2351% house edge) generates 106.0 units of cumulative action, an expected mathematical cost of −1.31 units, ±14.26 units of standard deviation, and a 78.6% session survival rate (21.4% bankroll ruin risk).

Column 2 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

  1. Column 3 starts, so use Rule 1: compare Column 2 with Column 1, 1 column further back.
  2. Column 2 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 2, the one that just finished, with Column 1.

DALS50 STOCHASTIC HORIZON

D'Alembert (DALS50) Over 50 Hands With a 20-Unit Bankroll

[DALS50-MECHANICS] Staking protocol DALS50 applies D'Alembert Arithmetic (+1u / -1u) (1-2-3-4-5-4-3) on Player across 50 hands with a 20-unit stop-loss. Increases the wager by +1 unit after a loss and reduces the wager by −1 unit (minimum 1u) after a win. Fast 45-minute mini-baccarat or two-thirds shoe sprint with a compact 20-unit buy-in.

[DALS50-EXPECTATION] By linearity of expectation, DALS50 cannot alter the 8-deck 1.2351% Player house edge: multiplying 106.0u cumulative action by −1.2351% locks in −1.31u expected drift with ±14.26u standard deviation. Avoids exponential bet explosions but drifts into elevated 5u–10u flat exposure when Player losses outnumber wins over 50+ deals. Remember that baccarat is an 18+ / 21+ game of chance; review /legal/responsible-gambling before setting session limits.

  • DALS50 bankroll boundary: 20u starting stack faces 21.4% ruin risk and 78.6% survival probability.

Table Reality Check

Myth vs. Truth

MythRunning D'Alembert over 50 hands with 20 units changes the mathematical expectation of the shoe.
TruthEvery hand in DALS50 faces the same 1.2351% Player house edge; scaling bet sizes to 106.0u total action scales expected cost to −1.31u while reshaping variance (±14.26u SD).
