The same audit shows the collapsed market figure quoting the dearest printing on 8.1% of English cards, by a median of 1.10x and a 99th percentile of 5.41x.",

    "Population: per printing rows inside the TCGplayer dump of September 4, 2026, restricted to products holding both a 1st Edition or 1st Edition Holofoil row and an Unlimited or Unlimited Holofoil row with a market price above zero. Every figure in this article is that day's reading. That is 195 products, 194 matched to catalog cards. Both legs are same product, same day, same venue, so no time alignment or cross venue join is involved, and the only derived quantity is a ratio of two independently recorded printing prices. Set level medians are reported with their n so the Gym Heroes weighting is visible. The publishing audit compares each product's collapsed market figure against the canonical printing price produced by the shared price rule, across 52,104 products and the 21,245 English cards among them. Base Set is absent from the pair census because the product carries a single blended holofoil row rather than separate printings. Superseded on coverage, not on method: we later filled per-printing rows for 1,342 more vintage cards and recensused the same question on 838 pairs in [We Remeasured First Edition](/articles/the-first-edition-census-four-times-over), which reports 2.59x and contains these 195 pairs as a subset. Read that one for the premium; this one remains the record of the publishing audit."
