8-Deck Two-Pip (Deuce) Depletion at 25% Penetration (5% Audit DEP380)

Removing 9 of 32 Two-Pip (Deuce) (Rank-2) cards at 25% penetration of a 8-deck (416-card) shoe leaves 23 Rank-2 cards inside a 312-card stub (DEP380), producing 45.8603% Banker wins, 44.6241% Player wins, 9.5156% Ties, and a 1.0569% 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

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.

How Two-Pip (Deuce) Depletion at 25% Depth Impacts 8D (5% Vig)

In combinatorial record DEP380, depleting 9 Rank-2 cards across 25% of a 8D (416-card) pack leaves 23 Two-Pip (Deuce) cards among 312 remaining cards, setting Banker win probability to 45.8603% and house edge to 1.0569% (5% Vig).

In 8D audit DEP380 (312/416 stub at 25% depth), depleting 2s shifts the (dep380-rank-2) probability of banker converting a (312c) two-card 4 or 5 into (dep380-rank-2·312c) a winning three-card 6 or 7. Removing 9 Rank-2 cards (+0.52 bps per card) alongside 5% Vig rules sets Tie hold to 14.3594% (9.5156% frequency).

Table Reality Check

Myth vs. Truth

MythWhen 9 Two-Pip (Deuce) cards leave a 8D shoe by 25% depth (DEP380), 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 (23/32 in 312 cards); Banker carries a -1.0569% expectation under 5%.
