  "title": "The Grading Throughput Index: 44,000 New Slabs a Week, and Half of Them Are Tens",
  "summary": "Our registry tracker recorded 82,723 new PSA slabs across just 1,097 tracked cards inside a 25-day window. Each card is snapshotted over part of that window, not all of it, so the rate those series imply is about 44,000 a week of certified supply, 53% of it gem mint, and it is pointed straight at the cards people are buying for scarcity.",

    "Population counts recorded daily by moonstone from PSA's public registry per tracked card (population_snapshots; series here span at least 7 days within an Aug 2-27, 2026 window). Throughput = each card's first-to-latest total-population delta divided by its own span and expressed per week, then summed across the 1,097 cards with multi-week series and net growth. Spans run 7 to 24 days and average 12.6, which is why the 82,723 slabs observed inside the window is a smaller number than 25 days of the summed rate: it is the observed total over partial, staggered spans, not a 25-day census. Gem share = summed gem-count deltas over summed total deltas. Cohort = cards our users and crons look at, skewing to modern chases; treat all levels as floors. JP set names shown as our catalog records them. Not financial advice."
