It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it.

A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
