4-Deck Eight-Pip Card Depletion at 25% Penetration (5% Audit DEP254)

Removing 5 of 16 Eight-Pip Card (Rank-8) cards at 25% penetration of a 4-deck (208-card) shoe leaves 11 Rank-8 cards inside a 156-card stub (DEP254), producing 45.8726% Banker wins, 44.5856% Player wins, 9.5418% Ties, and a 1.0067% Banker house edge under 5%.

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

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

Common table reading watchout: Comparing the wrong columns. Compare Column 4, the one that just finished, with Column 2.

Cockroach Pig Mark #2

This bead is at Row 2. Column 2 has a bead at Row 2 too → red (=).

  1. Column 5 goes down to Row 2, so use Rule 2: look 3 columns back, at Column 2.
  2. Column 2 has a bead at Row 2 too → red (=).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 2 stopped exactly one row above this bead.

How Eight-Pip Card Depletion at 25% Depth Impacts 4D (5% Vig)

In combinatorial record DEP254, depleting 5 Rank-8 cards across 25% of a 4D (208-card) pack leaves 11 Eight-Pip Card cards among 156 remaining cards, setting Banker win probability to 45.8726% and house edge to 1.0067% (5% Vig).

Why does Rank-8 carry a -0.50 bps per-card effect in DEP254? On Banker total 3, (DEP254) Banker draws against every Player (4D-25%) third card except 8; removing (DEP254·4D-25%) 8s eliminates Banker 3's sole standing exception, and at 25% penetration (11 Eight-Pip Card cards left in 156 4D cards), one-quarter of the shoe (dep254-4d) has exited the carrier and (11/16) winning banker wagers pay 0.95 (dep254-4d·11/16) to 1 after 5% house tax.

TABLEAU & SCOREBOARD SEPARATION · DEP254

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP254 · 4D)

Even at 25% penetration in DEP254 where 5 Rank-8 cards have exited a 4D shoe (11 left in 156 cards), derived-road red and blue entries measure structural regularity on the Big Road—not whether Banker (-1.0067% EV, 5% Vig) or Player (-1.2870% EV) is favored next.

  • DEP254 (4D 25%): 156/208 cards with 11/16 Rank-8 (1A).
  • DEP254 (Rank-8 split): 45.8726% Banker, 44.5856% Player, 9.5418% Tie in 156 4D cards (1B).
  • DEP254 (5% Vig EV): -1.0067% Banker, -1.2870% Player, -14.1240% Tie, 0.9344 SD at 25% (1C).
  • DEP254 (4D roads): red/blue marks log Big Road columns, never 11 Rank-8 stub count (1D).
Table Reality Check

Myth vs. Truth

MythWhen 5 Eight-Pip Card cards leave a 4D shoe by 25% depth (DEP254), 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-8 stub counts (11/16 in 156 cards); Banker carries a -1.0067% expectation under 5%.
