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.
• OP17 assumption-only Japanese collation proxy: exact English wrapper and card-price identities are retained, but no complete OP17 English or Japanese rarity ledger was established. Expected box marginals of 166 Common, 72 Uncommon, 39 Rare, 4 Leader, 4 Super Rare, 1 regular Secret Rare and 2 ordinary DON!! total 288 physical positions. Rarity marginals and regular Secret Rare conditioning remain explicit generic assumptions, not measured pull rates or a factory guarantee.
• The exact English ordinary roster contains 119 identities, OP17-001 through OP17-119: 45 Common, 30 Uncommon, 26 Rare, 6 Leader, 10 Super Rare and 2 Secret Rare. Roster headlines are not ordinary pool counts or rates: Bandai advertises 131+4 types and its Japanese page lists three SEC types, but EB04-061 Luffy 710857 is an SP treatment, not a third ordinary OP17 Secret Rare. Retain only regular Rocks.D.Xebec 709836 and Loki 710585 in the SEC pool; do not invent OP17-120 or import ordinary EB04 prices.
• The reviewed first-hand OP17 Japanese-box post shows only selected hits, with no complete C/UC/R/Leader/DON!! inventory, pack sequence, exact printing wave or opening interval. Comments disagree on hit guarantees and Pandaman replacement. Neither the post nor aggregated secondary hit claims establish a complete rate ledger for this English release. No case or box guarantee is adopted from them.
• All four ordinary booster DON!! designs 712747-712750 use their exact English Normal finish and positive Low prices despite Alternate Art titles. Gold/Special Foil DON!! 710859, 710860, 711420 and 711421 are removed before drawing, and retained ordinary DON!! outcomes normalized within the same slot. Two expected ordinary DON!! per box, equal four-design weights and replacement of Common positions are assumptions. Four published designs do not mean four draws per box or one per pack. No thirteenth card or separate fixed box-only DON!! is added.
• Each synthetic pack draws seven Common-or-DON!! positions at 83/84 Common and 1/84 DON!!, three Uncommon, one guaranteed Rare and one upgrade at 15/24 Rare, 4/24 Leader, 4/24 Super Rare and 1/24 regular Secret Rare. Slot assignment is an explicit modeling assumption. These independent draws preserve expected marginals, not guaranteed box counts, no-duplicate rules or case seeding. Draw all 288 positions from normalized retained pools before Sift and user filters; filters never backfill. Embedded pack EV is box EV divided by 24, including 2/24 expected DON!!.
• The six Pandaman variants 712593, 712605, 712617, 712633, 712643 and 712655 are excluded before drawing despite ordinary C/UC labels and Normal finishes; ordinary versions of those numbers remain eligible. All 50 exact unsupported game-card premiums, including SP, Manga, Super Alternate Art, Super Leader Alternate Art and Edward.Newgate Treasure Rare 710858, stay absent. DP-12 DON!! 715681/715682 are separate purchase-product bonuses, not contents of booster box 704752. No external purchase, release-event or tournament promotion adds fixed baseline value without exact box-inclusion evidence. Every retained English SKU must have a positive Low price; equal weights within each rarity/finish pool are assumptions.
• 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.
