Limitations

• collation.cardsPerPack and collation.packsPerProduct: the product uses 12 cards per pack and 24 packs per English booster box; those physical wrapper counts do not establish rarity-slot probabilities.
• collation.caseStructure: box-level hit counts and display/case correlations are unresolved for the exact English North America printing.
• evidence.sample: null because no reviewed observation provides a complete, attributable sample with exact unit, size, method, North America printing, and observation interval.
• pricing.coverage: exact TCGCSV identity is known, but modeled row and expected-mass coverage have not been measured.
• Modeling policy approved 2026-09-04: every supported ordinary card in the same slot, rarity, treatment, and finish pool receives one equal positive selection weight. This is a transparent modeling assumption where the publisher or empirical sample gives pool odds but not card-level sheet weights.
• Best Evidence — Japanese collation proxy: exact English wrapper and card-price identities are combined with an owner-approved Japanese-product collation proxy because a complete English rate ledger is not published. This is an estimate, not a factory guarantee.
• Only booster-pack slot counts and rarity probabilities are proxied. Card identities, treatments, TCGplayer Low prices, sealed-product identity, language, region, release date, and any explicitly modeled fixed bonus come from the exact English release.
• The proxy is first-order and product-family-specific. No display or case correlation is inherited, and no target is used as a donor for another target.
• Within each retained English rarity/treatment pool, exact positively priced card SKUs use equal positive weight where publisher sheet weights are unavailable.
• Per 24-pack English box proxy: 166 Common, 72 Uncommon, 39 Rare, 4 Leader, 4 Super Rare, and 1 retained Secret Rare fill 286 game-card positions. Two exact English parallel DON!! cards replace two assumed Common positions within 288 physical cards, following the one-per-Japanese-box pattern scaled to the double-card English wrapper and corroborated by an English-box observation.
• Replace this proxy when a complete, attributable English collation ledger or publisher rate table becomes available for the exact release.
• Bandai's exact English OP-04 roster contains 124 game-card types plus one DON!! type: 45 Common, 30 Uncommon, 26 Rare, 6 Leader, 10 Super Rare, 2 Secret Rare, 5 Special cards, and 1 DON!! card, with 25 alternate-art types also disclosed. The no-chase model retains all 119 ordinary C/UC/R/L/SR/SEC English identities and excludes the five Special and 25 unsupported alternate-art chase identities before drawing.
• Japanese OP-04 uses 24 six-card packs and its reviewed box pattern reports four Leaders, three or four Super Rares, zero or one Secret Rare, one parallel-or-Secret hit, and one parallel DON!! card. The English model scales that first-order structure to 24 twelve-card packs; after excluded premium hits are removed, their positions are conditioned onto eligible ordinary English pools rather than retained as zero-EV outcomes.
• The exact English TCGplayer DON!! identity is product 517476, DON Card Alternate Art. The box model includes two copies: the Japanese one-per-box pattern is doubled for the English wrapper and an English OP-04 box report independently corroborates two DON!! cards. This remains a disclosed proxy estimate, not a publisher factory guarantee.
• The two expected DON!! outcomes replace two assumed Common positions inside the advertised wrapper, producing 288 modeled physical cards per box. Exact replacement rarity and pack assignment are unresolved; embedded pack EV includes the average 2/24 DON!! contribution.
• The six OP-03 Dash Pack reprints in the OP-04 marketplace group belong to Bandai's first-come, brick-and-mortar Hobby Store Dash Pack purchase campaign. They are not sealed inside every OP-04 booster box and are excluded from both booster and box EV. TCGplayer products 517477 and 517478 likewise belong to the separate DP-01 Special DON!! Card Pack and are not OP-04 booster-box contents.
• No within-box pack assignment or case covariance is modeled for the two DON!! inserts, and the store campaign bonus is not added to the sealed-box identity even when a retailer originally supplied it alongside a qualifying purchase.
• No-chase redraw policy approved 2026-09-04: Curio, Enchanted, alternate-art, parallel, showcase, serialized, signature, premium-rarity, promotional, and any other card or treatment without a supported pull rate are excluded. A chase hit is redrawn from the applicable supported ordinary pool, so excluded cards occupy no modeled outcome.
• Simulation ordering is draw the complete disclosed no-chase product first, record that draw, and only then apply Sift or another user filter. Sift never changes or backfills the completed modeled draw.
