What is the set value?: What it costs to own one Near Mint copy of every printing in the set, at fair value. 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 change beside the set value is that line over 30 days, or over 7 for a set too new for a month. Beside it, the set without the chases (every card counted the same) 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.
