4-Deck Two-Pip (Deuce) Depletion at 40% Penetration (4% Audit DEP201)

Removing 7 of 16 Two-Pip (Deuce) (Rank-2) cards at 40% penetration of a 4-deck (208-card) shoe leaves 9 Rank-2 cards inside a 125-card stub (DEP201), producing 45.8742% Banker wins, 44.5840% Player wins, 9.5418% Ties, and a 0.5448% Banker house edge under 4%.

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

Column 4 has 1 bead. Column 2 has 2 beads. Different depth → blue (≠).

  1. Column 5 starts, so use Rule 1: compare Column 4 with Column 2, 2 columns further back.

How Two-Pip (Deuce) Depletion at 40% Depth Impacts 4D (4% Vig)

At 40% penetration of a 208-card (4D) shoe, state DEP201 isolates 7 dealt Rank-2 cards (9 remaining inside 125 stub cards), yielding 45.8742% Banker wins, 44.5840% Player wins, and 0.9341 per-hand standard deviation under 4%.

When 7 Rank-2 cards exit a 4D shoe by 40% penetration (DEP201, 9 left in 125 cards), depleting 2s shifts the (dep201-rank-2) probability of banker converting a (125c) two-card 4 or 5 into (dep201-rank-2·125c) a winning three-card 6 or 7, combining a +0.52 bps rank vector with 4% settlement (-0.5448% Banker EV).

TABLEAU & SCOREBOARD SEPARATION · DEP201

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP201 · 4D)

Statistical verification of DEP201 (4D, 40% penetration, 9 Two-Pip (Deuce) cards in 125 stub cards) demonstrates why single-rank depletion (7 Rank-2 dealt) shifts edges by basis points around -0.5448% (4% Vig).

  • DEP201 (4D 40%): 125/208 cards with 9/16 Rank-2 (2A).
  • DEP201 (Rank-2 split): 45.8742% Banker, 44.5840% Player, 9.5418% Tie in 125 4D cards (2B).
  • DEP201 (4% Vig EV): -0.5448% Banker, -1.2902% Player, -14.1235% Tie, 0.9341 SD at 40% (2C).
  • DEP201 (4D roads): red/blue marks log Big Road columns, never 9 Rank-2 stub count (2D).
Table Reality Check

Myth vs. Truth

MythWhen 7 Two-Pip (Deuce) cards leave a 4D shoe by 40% depth (DEP201), Big Eye Boy red or blue marks show whether Banker or Player will win next.
TruthDerived-road red and blue marks only compare Big Road column lengths and never track Rank-2 stub counts (9/16 in 125 cards); Banker carries a -0.5448% expectation under 4%.
