How this chart is drawn

One value a day. The 1Y and MAX views show one point a week.

TCGplayer's own chart is drawn per condition, so it can differ from this one.

Compared with its group

Vs its group
~30d+129.3 pts~90d+368.4 pts

A gap in percentage points: this card's change minus the typical change of Pokémon cards from sets released 2000-2015 (ungraded, English), over each card's own window rather than an exact 30 or 90 days. On ~30d: this card +131.8%, the typical card +2.5%. On ~90d: this card +380.5%, the typical card +12.1%. The group spans every price level, so it is an era-and-format population, not a set of comparable cards.
