Azur Lane Vol.2 Booster Display EV Calculator

Region

Unreported; English territory and printing are not established by the indexed post text

Case correlations

Preserved

Method

One named post reports two complete Azur Lane Vol.2 cases. Case 1 reports 6 ordinary RRR and 63 ordinary SR; case 2 reports 7 ordinary RRR and 62 ordinary SR. Reported SP and RRR+ counts are chase evidence only and are excluded completely. The post does not provide pack order, base-rarity composition, per-card pool weights, printing, wave, or a territory that can be tied to the English TCGplayer SKU set.

Limitations

• Bushiroad publishes the physical recipe: 8 cards per pack, 12 packs per display, and 24 displays per carton.
• Bushiroad lists 130 normal card types and 181 parallel card types. Type counts do not establish pull probabilities, replacement rules, per-display guarantees, or within-pool card weights.
• The reviewed publisher territory includes the United States and Canada. This record does not generalize rates to other English territories.
• Exact first-release pack and display identities; the empirical case report remains insufficient for a model.
• Prominently labeled empirical evidence: one indexed post reports two cases, but its observation interval was not reported and remains null.
• The empirical printing wave was not reported and remains null.
• The empirical printing detail was not reported and remains null.
• The source text reviewed does not establish English territory, exact printing, pack order, base-rarity composition, or individual-SKU pool weights. Its two case totals therefore remain negative evidence for sufficiency, not a calculator model.
• The reported SP and RRR+ case counts are excluded chase observations and do not create slots, probability mass, zero-EV placeholders, redraws, or an implied ordinary distribution.
• Modeling policy approved 2026-07-24: 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.
• No-chase policy approved 2026-07-24: signed, serialized, hot-stamped, premium, special, secret-plus, parallel, promotional, and equivalent chase cards and branches do not exist in this model. The exact physical card count is drawn only from the supported ordinary pool; there is no simulated chase hit, zero-EV occupied outcome, redraw, backfill, or renormalization.
• 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.
• Best-evidence Weiss Schwarz baseline approved 2026-07-24: the publisher's exact cards-per-pack and packs-per-display are modeled as ordinary draws from the exact English TCGCSV normal-card pool. This is a transparent assumption-based estimate, not a claim about factory rarity collation, replacement rules, display guarantees, or pack correlation.
• When multiple ordinary physical variants share one published card number, their positive weights divide one card-number weight equally so variants do not inflate the publisher's normal-card type count.
