What is the typical single?: The median fair value of the set's Near Mint English singles — the price in the middle, so one chase card can't drag it up. Fair value comes from real sales only; the marketplace's Market Price is shown on card pages but never counted.
What does the index line show?: The Set Value Index: one Near Mint copy of every printing at fair value, compared week to week on the same printings, so it moves with the set's value — the chase cards most. It starts at 100; the 90-day figure is that line over the last quarter. Beside it, the typical card (every card counted the same, chases left out) and the chases on their own.
How is popularity scored?: Out of 100, against the rest of the game: how much the set's cards sell for, how many of them sell each week, how many cards it holds and how its index has moved. It ranks sets; it isn't a price.
