Limitations

• Bandai publishes 12 physical cards per English-US pack, but it does not publish the complete ordinary slot probabilities, replacement mapping, or per-card weights.
• TCGCSV category 86 group 24693 contained 108 card products, 108 with a non-null TCGplayer Low field, when reviewed. The 111 price rows split into 73 Normal and 38 Holofoil rows. This establishes current row availability only; without a reviewed model it does not establish expected-mass coverage.
• Normal and Holofoil are marketplace subtype labels, not automatically frame/style Treatments. Every duplicate-number and finish row must be mapped to an exact SKU before it can enter a model.
• The no-chase baseline has no separate English collector product to use instead. Before approval, every +, ++, SP, Link Rare, premium Resource, and other chase SKU and branch must be enumerated and omitted entirely.
• The English-US publisher page specifies twelve cards, without +1, but no rarity table. Its filtered English checklist resolves 45 Common, 24 Uncommon, 15 Rare, six Legend Rare and T-025, plus sixteen + parallels and ST10-006 Phoenix LR++. Checklist counts establish identities, not pull probabilities.
• EB01's two-display opening report supplies partial high-card/token evidence only. The 6 C/4 U allocation, two interchangeable high positions, inferred ordinary Rare total and equal within-pool weights remain explicit assumptions. No other set's opening supplies EB01 rates, no ordinary Resource or basic EX is imported, and no external starter/release-event bonus is added.
• Modeling policy approved 2026-09-03: 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 pack estimate: an assumed 6 Common and 4 Uncommon, plus two Rare/LR/Token draws weighted 18/23, 4/23 and 1/23 after premium removal. The 24-pack English EB01 display has exactly 288 physical cards and no +1 support slot.
• Replace this proxy when a complete, attributable English collation ledger or publisher rate table becomes available for the exact release.
• EB01-specific English reports supplement the program's Japanese proxy label. Bandai specifies twelve cards per English pack and six per Japanese pack; no extra support is guaranteed. The official English checklist has 45 Common, 24 Uncommon, 15 Rare, six Legend Rare, T-025 Gundam Exia and 17 premium printings. These are identity counts, never pull probabilities; no basic EX, Resource or ordinary ST10 card is imported.
• A first-person Central European opening reports two EB01 displays, each with eight ordinary LR, two parallels and two Exia Tokens. A separate EB01-specific comment says its Token replaces a Rare. Assuming two high positions per pack infers 36 ordinary Rares per display; removing both parallels leaves 36:8:2 retained R/LR/Token mass, normalized to 18/23, 4/23 and 1/23 before drawing all 48 high positions. The inferred Rare count and independent interchangeable slots are small-sample assumptions, not factory guarantees; other EB01 reports describe seven LR and three parallels.
• No complete EB01 pack-by-pack low-rarity ledger was accessible. Six Common and four Uncommon per twelve-card pack is an explicit allocation assumption filling ten low positions, not a measured English or Japanese split and not borrowed from another set's observations. Rough reported per-card duplicate counts do not reconcile to a complete box and are not used as probabilities. Equal weights within each exact ordinary rarity/finish pool are also assumptions.
• All 91 exact ordinary English SKUs must have matching positive TCGplayer Low prices. EX in an ordinary card's name, Premium Unit Assembly and SP Conversion Chips do not denote chase treatments. The sixteen + parallels and Phoenix Gundam (Power Unleashed) (EX) ST10-006 LR++ product 702815 are absent before drawing. That cross-numbered LR++ belongs to EB01; it does not justify importing its ordinary starter version.
• Draw all 288 physical cards before Sift or user filters; filtering never backfills. No topper, purchase promo, release-event Resource, DON!! or starter bonus enters the display. Embedded pack EV is full display EV divided by 24. No no-duplicate rule, guaranteed token count, pack order, box seeding or case covariance is preserved, and simulation bands are not confidence intervals for factory collation.
• No-chase redraw policy approved 2026-09-03: 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.
