How to read this board
How fast a card's PSA 10 population is growing compared with its own recent average. A 5× expansion means slabs are entering roughly five times faster than usual.
Rising population is one input into price, not a prediction. A card with strong demand can absorb a lot of new supply without moving.
Going from 4 slabs to 12 is a 3× expansion on almost no absolute volume. Read the multiple next to the population and the per-month count.
