STAGE 2 STRESS TEST · 2-1-2 MANHATTAN VS FLAT BETTING

2-1-2 Manhattan Progression vs. Flat 1-Unit Baseline — 9-Hand Dragon Streak Shoe under 5% Banker Commission (75-Hand Stress Test)

Stress test S270-0 quantifies 2-1-2 Manhattan Progression (2-1-2-3-4-5) against Flat 1-Unit Baseline (1-1-1-1 constant unit) inside a 80-unit bankroll over 75 hands (5% Comm Streak, streak), where a 60-unit table ceiling produces 10.47% vs 4.80% ruin rates and computes 0.62u in capital-bounded vigorish drag. Because every 8-deck coup is statistically independent under 5% Banker Commission (0.95:1) (1.0579% edge), progression rules alter drawdown speed and table-cap collisions without changing per-hand expectation.

Step-by-Step Mark Proofs (Rule 1 & Rule 2)
Big Eye Boy Mark #2

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.

Small Road Mark #2

This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).

  1. Column 3 goes down to Row 3, so use Rule 2: look 2 columns back, at Column 1.
  2. Column 1 stopped at Row 2, one row above → blue (≠).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.

Cockroach Pig Mark #2

This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).

  1. Column 4 goes down to Row 3, so use Rule 2: look 3 columns back, at Column 1.
  2. Column 1 stopped at Row 2, one row above → blue (≠).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.
