8-Deck Four-Pip Card Depletion at 25% Penetration (5% Audit DEP398)

Removing 9 of 32 Four-Pip Card (Rank-4) cards at 25% penetration of a 8-deck (416-card) shoe leaves 23 Rank-4 cards inside a 312-card stub (DEP398), producing 45.8610% Banker wins, 44.6234% Player wins, 9.5156% Ties, and a 1.0554% 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.

FINITE-SHOE ENUMERATION · DEP398

How Four-Pip Card Depletion at 25% Depth Impacts 8D (5% Vig)

Under 5% settlement (5% Vig), combinatorial state DEP398 models a 8D carrier with 312 cards left (25% dealt) and 23/32 Four-Pip Card cards remaining, producing a 1.0554% Banker edge versus 1.2376% on Player.

Removing 4s produces the (DEP398-Rank-4) single largest per-card shift toward (312c) Banker (and away from Player) (DEP398-Rank-4·312c) of any rank in the shoe. Because 9 of 32 Four-Pip Card cards are absent in DEP398 at 25% 8D penetration (312 cards left), per-card sensitivity (+1.19 bps) interacts directly with quarter-shoe 25% penetration depth (DEP398) under standard 5% Banker commission (Rank-4) (0.95:1 payout).

TABLEAU & SCOREBOARD SEPARATION · DEP398

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP398 · 8D)

Even at 25% penetration in DEP398 where 9 Rank-4 cards have exited a 8D shoe (23 left in 312 cards), derived-road red and blue entries measure structural regularity on the Big Road—not whether Banker (-1.0554% EV, 5% Vig) or Player (-1.2376% EV) is favored next.

  • DEP398 (8D 25%): 312/416 cards with 23/32 Rank-4 (7A).
  • DEP398 (Rank-4 split): 45.8610% Banker, 44.6234% Player, 9.5156% Tie in 312 8D cards (7B).
  • DEP398 (5% Vig EV): -1.0554% Banker, -1.2376% Player, -14.3594% Tie, 0.9332 SD at 25% (7C).
  • DEP398 (8D roads): red/blue marks log Big Road columns, never 23 Rank-4 stub count (7D).
Table Reality Check

Myth vs. Truth

MythWhen 9 Four-Pip Card cards leave a 8D shoe by 25% depth (DEP398), 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-4 stub counts (23/32 in 312 cards); Banker carries a -1.0554% expectation under 5%.
