4-Deck Nine-Pip Card Depletion at 80% Penetration (Super 6 Audit DEP269)

Removing 15 of 16 Nine-Pip Card (Rank-9) cards at 80% penetration of a 4-deck (208-card) shoe leaves 1 Rank-9 cards inside a 42-card stub (DEP269), producing 45.8720% Banker wins, 44.5862% Player wins, 9.5417% Ties, and a 1.4072% Banker house edge under Super 6.

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 Nine-Pip Card Depletion at 80% Depth Impacts 4D (Super 6)

When a 4D shoe reaches 80% cut-card depth (42 of 208 cards undealt, state DEP269) with 15 Nine-Pip Card cards removed and 1 remaining, Player wins 44.5862% (1.2858% edge) while Banker wins 45.8720% (1.4072% edge under Super 6).

Combinatorial weighting in DEP269 (42 cards left from 208 at 80% depth) is governed by two rules: rank 9 paired with (dep269) any ten or face card (4d-80%) creates an unbeatable two-card natural (dep269·4d-80%) 9 that halts all third-card drawing on both sides, and only 20% of the (dep269-4d) initial shoe remains undealt while (1/16) winning banker 6 hands forfeit (dep269-4d·1/16) half their payout (-0.23 bps per Rank-9 removed).

TABLEAU & SCOREBOARD SEPARATION · DEP269

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP269 · 4D)

Even at 80% penetration in DEP269 where 15 Rank-9 cards have exited a 4D shoe (1 left in 42 cards), derived-road red and blue entries measure structural regularity on the Big Road—not whether Banker (-1.4072% EV, Super 6) or Player (-1.2858% EV) is favored next.

  • DEP269 (4D 80%): 42/208 cards with 1/16 Rank-9 (6A).
  • DEP269 (Rank-9 split): 45.8720% Banker, 44.5862% Player, 9.5417% Tie in 42 4D cards (6B).
  • DEP269 (Super 6 EV): -1.4072% Banker, -1.2858% Player, -14.1243% Tie, 0.9402 SD at 80% (6C).
  • DEP269 (4D roads): red/blue marks log Big Road columns, never 1 Rank-9 stub count (6D).
Table Reality Check

Myth vs. Truth

MythWhen 15 Nine-Pip Card cards leave a 4D shoe by 80% depth (DEP269), 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 (1/16 in 42 cards); Banker carries a -1.4072% expectation under Super 6.
