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.

New slabs a week against the recorded PSA population.
