All figures are reproduced from those studies without adjustment. Card records (names, identifiers, artwork) come from TCGdex and never determine a tier rate.
If a figure is updated upstream, this repo will change the rate and the date, and — where
the old value is still reported somewhere in the source — keep it as alternateRatePct.
