Identify what the percentage measures
Theoretical EV uses a complete outcome distribution. Observed sample return totals estimated pull value and divides it by spending in a particular sample. Illustrative figures are examples. Those three should never be presented as the same result.
A site should label which it reports, when the sample was collected and whether the product changed afterwards. This checklist is an editorial standard, not an accreditation or a claim that Verified Repack has completed those audits.
Look for a reproducible pull log
Useful records include purchase date, product and tier, amount paid, discounts, pull identity, grade, certification details where relevant, and the valuation used. A receipt and a card photo are stronger than a summary saying 'we tested it.'
Hypothetical sample: ten $50 packs cost $500 and produce cards estimated at $400. The observed card-value return is 80%. That describes those ten purchases; it doesn't prove the true EV of the whole product.
Check how values and cash proceeds were measured
Ask for matching sold comps and their dates, or an explicit explanation of the platform's valuation method. Keep asking prices, estimated card values, accepted buybacks and net sale proceeds separate.
eBay's Product Research can show actual sold prices, including accepted Best Offers. A tool name alone still isn't evidence: the relevant matched transactions should support the card values used.
Look for uncertainty and conflicts
A few rare pulls can dominate a small sample's mean. Ask how packs were selected, whether the sample missed tiers and how uncertainty was assessed. A larger sample doesn't cure biased selection or inaccurate valuations.
Check compensation disclosures and whether evidence is available for negative as well as positive conclusions. Treat unexplained scores and unsupported fraud allegations cautiously. Use this checklist on our pages too; Verified Repack publishes no return or EV figures for any platform.
