When a user creates a Talent Passport, we check all Credentials and calculate their Builder Score. We repeat the same global recalculation, for every user, every 14 days. This is a costly computation process that shouldn't be done too frequently.
The Credentials can be updated manually by the user, by clicking on the "Check" button (max 1 check/hour).
There's also a "Refresh" button in the Profile Settings, that refreshes your profile data, but doesn't recalculate the Builder Score.
