Supportive1Context1

Each stamp is one fixed formula applied identically to every card. Supportive and caution mark a reading that cuts the same way for anyone holding the card. Context marks a fact that is good news to a buyer and bad news to a holder, so the desk does not pick a side.

Printing rankContext

CHEAPEST PRINTING

This printing's raw price against every tracked printing of the Pokémon.

Character demandSupportive

CHARACTER BID

The species demand index, a weighted percentile across every tracked species.

Every verdict is a disclosed formula over recorded data, applied with the same fixed thresholds to every card. No discretionary price forecasting is used, and the arithmetic is printed so it can be reproduced.
