1-Deck Eight-Pip Card Depletion at 25% Penetration (5% Audit DEP074)

Removing 1 of 4 Eight-Pip Card (Rank-8) cards at 25% penetration of a 1-deck (52-card) shoe leaves 3 Rank-8 cards inside a 39-card stub (DEP074), producing 45.9590% Banker wins, 44.5254% Player wins, 9.5156% Ties, and a 0.8643% 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 2. Column 2 has a bead at Row 2 too → red (=).

  1. Column 4 goes down to Row 2, so use Rule 2: look 2 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.

Cockroach Pig Mark #2

Column 4 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

  1. Column 5 starts, so use Rule 1: compare Column 4 with Column 1, 3 columns further back.
  2. Column 4 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 4, the one that just finished, with Column 1.

FINITE-SHOE ENUMERATION · DEP074

How Eight-Pip Card Depletion at 25% Depth Impacts 1D (5% Vig)

Finite-shoe specification DEP074 tracks Rank-8 removal at 25% depth in 1-deck play: with 3 of 4 Eight-Pip Card cards left in the 39-card stub, Tie incidence is 9.5156% and Banker expectation settles at -0.8643% (5% Vig).

Why does Rank-8 carry a -0.50 bps per-card effect in DEP074? On Banker total 3, (DEP074) Banker draws against every Player (1D-25%) third card except 8; removing (DEP074·1D-25%) 8s eliminates Banker 3's sole standing exception, and at 25% penetration (3 Eight-Pip Card cards left in 39 1D cards), one-quarter of the shoe (dep074-1d) has exited the carrier and (3/4) winning banker wagers pay 0.95 (dep074-1d·3/4) to 1 after 5% house tax.

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP074 · 1D)

Learners auditing DEP074 (1D at 25% depth, 3/4 Rank-8 in 39 stub cards) can verify that 5% house hold (0.8643% Banker, 1.4336% Player, 14.3598% Tie) operates independently of prior Big Road streaks.

  • DEP074 (1D 25%): 39/52 cards with 3/4 Rank-8 (4A).
  • DEP074 (Rank-8 split): 45.9590% Banker, 44.5254% Player, 9.5156% Tie in 39 1D cards (4B).
  • DEP074 (5% Vig EV): -0.8643% Banker, -1.4336% Player, -14.3598% Tie, 0.9344 SD at 25% (4C).
  • DEP074 (1D roads): red/blue marks log Big Road columns, never 3 Rank-8 stub count (4D).

Myth vs. Truth

MythWhen 1 Eight-Pip Card cards leave a 1D shoe by 25% depth (DEP074), 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 (3/4 in 39 cards); Banker carries a -0.8643% expectation under 5%.
