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.
• 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.
• EB02 assumption-only Japanese collation proxy: exact English wrapper and card-price identities are retained, but no complete EB02 English or Japanese rarity ledger was established. Expected box marginals of 240 Common, 39 Rare, 4 Leader, 4 Super Rare and 1 regular Secret Rare total 288 physical positions. These are explicit generic assumptions, including regular Secret Rare conditioning, not measured EB02 pull rates or a factory guarantee. No other set's observations are used as EB02 evidence.
• The exact English ordinary roster is EB02-001 through EB02-061: 29 Common, 21 Rare, 1 Leader, 9 Super Rare and 1 Secret Rare. C and Leader use Normal finish; R, SR and SEC use Foil. The advertised 87 card types include 26 Special leader reprints carrying EB01/OP05/OP06/OP07/OP08 numbers. Those exact gold-foil treatments are not ordinary reprints or 26 extra ordinary Leader choices. All 61 retained exact English SKUs require positive TCGplayer Low; missing ordinary prices fail classification instead of shrinking the pool. Equal per-card weights within each rarity/finish pool are assumptions. No Japanese card prices enter this model.
• The first-hand Japanese EB02 two-box opening published January 25, 2025 shows Rare, theme-song Rare, SR and parallel results but no complete Common/Leader inventory or pack sequence. The English EB02 two-case selected-hit report has an EB01 typo in its opening sentence, corrected hit-count inconsistencies, no full C/R/Leader inventory, no exact North America printing wave and no precise opening interval. Its six-SR and four-SEC-per-case assertions are not adopted as a complete rate ledger. Neither partial opening establishes every retained slot, replacement relationship or case guarantee; evidence.sample remains null.
• The English publisher's wrapper image says twelve cards; the exact English retail box listing corroborates twenty-four boosters. The Japanese six-card wrapper is not the English product. Each synthetic English pack draws ten Common, one assumed guaranteed Rare and one upgrade at 15/24 Rare, 4/24 Leader, 4/24 Super Rare and 1/24 regular Secret Rare. Slot placement and all rarity probabilities are assumptions. Independent draws preserve expected marginals, not guaranteed box counts, no-duplicate rules or case seeding. Draw all 288 positions before Sift and user filters; filters never backfill. Embedded pack EV is box EV divided by 24.
• All 44 exact unsupported premium SKUs are absent before drawing: 26 Special gold-foil leader reprints plus 18 alternate-art/Manga variants. Normalize retained outcomes within each applicable slot. Regular Leader Luffy 629100 and regular Secret Rare Luffy 629165 remain eligible; their premiums 629101, 629166 and 629167 never occupy zero-EV positions. Unpriced Special leaders 629086, 629171, 629184 and 629188 are intentionally excluded premiums, not ordinary coverage gaps. EB02 has no separate collector product, so this documented no-chase baseline applies to its booster box. No DON!! card is published in this product's roster or present in the English group. Do not import another release's ordinary/Gold DON, invent a thirteenth card or add an unsupported topper, purchase, release-event or tournament bonus.
• 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.
