4-Deck Nine-Pip Card Depletion at 75% Penetration (4% Audit DEP268)

Removing 14 of 16 Nine-Pip Card (Rank-9) cards at 75% penetration of a 4-deck (208-card) shoe leaves 2 Rank-9 cards inside a 52-card stub (DEP268), producing 45.8722% Banker wins, 44.5861% Player wins, 9.5418% Ties, and a 0.5488% Banker house edge under 4%.

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 Nine-Pip Card Depletion at 75% Depth Impacts 4D (4% Vig)

In combinatorial record DEP268, depleting 14 Rank-9 cards across 75% of a 4D (208-card) pack leaves 2 Nine-Pip Card cards among 52 remaining cards, setting Banker win probability to 45.8722% and house edge to 0.5488% (4% Vig).

Mechanical draw trees in DEP268 reflect how when 9s are depleted (dep268-rank-9) late in the shoe, more (52c) hands bypass four-card natural resolution (dep268-rank-9·52c) and enter the five- and six-card tableau. At 75% 4D depth (2 Rank-9 left of 16 in 52 cards, -0.23 bps slope), three-quarters of the shoe (dep268-4d) has been dealt and winning (2/16) banker wagers return 0.96 units (dep268-4d·2/16) net per unit risked.

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP268 · 4D)

For DEP268 (52 remaining cards in a 208-card 4D shoe at 75% depth), tracking all 14 exited Rank-9 cards moves Banker win rate to 45.8722% (-0.5488% EV, 4% Vig) and Player to 44.5861% (-1.2861% EV).

  • DEP268 (4D 75%): 52/208 cards with 2/16 Rank-9 (1A).
  • DEP268 (Rank-9 split): 45.8722% Banker, 44.5861% Player, 9.5418% Tie in 52 4D cards (1B).
  • DEP268 (4% Vig EV): -0.5488% Banker, -1.2861% Player, -14.1242% Tie, 0.9397 SD at 75% (1C).
  • DEP268 (4D roads): red/blue marks log Big Road columns, never 2 Rank-9 stub count (1D).
Table Reality Check

Myth vs. Truth

MythWhen 14 Nine-Pip Card cards leave a 4D shoe by 75% depth (DEP268), 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-9 stub counts (2/16 in 52 cards); Banker carries a -0.5488% expectation under 4%.
