8-Deck Eight-Pip Card Depletion at 25% Penetration (5% Audit DEP434)

Removing 9 of 32 Eight-Pip Card (Rank-8) cards at 25% penetration of a 8-deck (416-card) shoe leaves 23 Rank-8 cards inside a 312-card stub (DEP434), producing 45.8592% Banker wins, 44.6253% Player wins, 9.5156% Ties, and a 1.0591% Banker house edge under 5%.

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

Quantitative proof DEP434 documents 8D rank depletion at 25% depth: 9 exited Rank-8 cards leave 23 of 32 in the 312-card stub, generating 45.8592% Banker wins (-1.0591% EV under 5% Vig) and 44.6253% Player wins.

Depleting 8-pip cards also (DEP434-Rank-8) lowers two-card Natural 8 lockouts (312c) when paired with zero-point tens (DEP434-Rank-8·312c) and court cards. Because 9 of 32 Eight-Pip Card cards are absent in DEP434 at 25% 8D penetration (312 cards left), per-card sensitivity (-0.50 bps) interacts directly with quarter-shoe 25% penetration depth (DEP434) under standard 5% Banker commission (Rank-8) (0.95:1 payout).

TABLEAU & SCOREBOARD SEPARATION · DEP434

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP434 · 8D)

While DEP434 tracks 9 removed Eight-Pip Card cards across 25% of a 416-card (8D) shoe (312 remaining, 1.0591% 5% Vig edge), Big Eye Boy (lookback 1), Small Road (lookback 2), and Cockroach Pig (lookback 3) evaluate only Big Road column shapes.

  • DEP434 (8D 25%): 312/416 cards with 23/32 Rank-8 (5A).
  • DEP434 (Rank-8 split): 45.8592% Banker, 44.6253% Player, 9.5156% Tie in 312 8D cards (5B).
  • DEP434 (5% Vig EV): -1.0591% Banker, -1.2339% Player, -14.3598% Tie, 0.9344 SD at 25% (5C).
  • DEP434 (8D roads): red/blue marks log Big Road columns, never 23 Rank-8 stub count (5D).
Table Reality Check

Myth vs. Truth

MythWhen 9 Eight-Pip Card cards leave a 8D shoe by 25% depth (DEP434), 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 (23/32 in 312 cards); Banker carries a -1.0591% expectation under 5%.
