Limitations

• Bandai publishes 13 physical cards per English-US pack and 139+20 card types, but it does not publish the complete ordinary slot probabilities, replacement mapping, or per-card weights.
• TCGCSV category 86 group 24522 contained 202 card products, 202 with a non-null TCGplayer Low field, when reviewed. The 207 price rows split into 109 Normal and 98 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.
• Bandai identifies seven Special card types but does not publish their insertion or replacement rates.
• 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.
• The English thirteen-card wrapper and exact ordinary printings are source-backed. Selected SP-bearing English GD03 openings inform the retained conditional 37 Rare:8 Legend Rare high-slot marginal after premium exclusion. Six Common, four Uncommon, two interchangeable high positions and uniform inner/support allocation remain disclosed assumptions. These selected samples do not establish complete English-US factory rates or an SP guarantee.
• Card identities, physical finishes and product units are English-US. European-distribution English openings and partial first-hand English ledgers supply empirical context; no measured Japanese rate ledger is used for this retained GD03 recipe.
• The approximation is first-order and GD03-specific. No display or case correlation is inferred, and no other set supplies GD03 rates.
• Within each retained English rarity/treatment pool, exact ordinary printings use equal positive weight where publisher sheet weights are unavailable. Missing quotes do not remove identities or reweight the draw.
• Per pack estimate: 6 Common, 4 Uncommon, two Rare-or-Legend-Rare draws weighted 37/45 Rare and 8/45 Legend Rare after removing the observed parallels and SP, plus one ordinary Resource/EX Resource/EX Base/Unit Token. The 24-pack display contains 312 physical cards and 128/15 (about 8.53) expected ordinary Legend Rares.
• Revisit these assumptions when a complete, attributable English collation ledger or publisher rate table becomes available for the exact release.
• GD03-specific English evidence supplies partial empirical context: a photographed European-distributed 24-pack opening and the ZEROsystem author's first three directly opened box ledgers each have eight ordinary LRs, two parallel game cards and one SP. Conditioning their high-slot population on removing all three premium outcomes gives 37 Rare to 8 LR. These SP-bearing samples do not establish a population SP rate or English-US case guarantee; reports of boxes without SP show that the marginal can vary.
• The English ordinary roster is 50 Common, 36 Uncommon, 34 Rare and 12 Legend Rare, with exact collector-number-to-product-ID maps. All seven SP reprints and every +/++ parallel are absent before drawing. Publisher checklist counts establish identities only, never pull probabilities. A Healthy Curiosity GD03-101 is an ordinary Rare despite its name containing the letters Curio.
• The +1 support pool contains 20 exact Normal English SKUs: R-020 through R-029, T-013 through T-020, and basic EXB-001/EXR-001 from marketplace group 24221 products 643300/643301. Retained supports receive assumed equal 1/20 weights after premium Resource removal; no support enters the six-Common game-card positions.
• Equal per-card weights, interchangeable high-slot marginals and independent draws are assumptions, with no box seeding, uniqueness, pack sequence or case covariance preserved. Draw all 312 cards before Sift or user filters; filters do not backfill. There is no topper, DON!!, purchase promo or starter bonus. Embedded pack expectation has the display expectation divided by 24 including its support position; pack Low/Mid/High are independently simulated from one complete thirteen-card pack; simulation bands are not factory-collation confidence intervals.
• 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.
