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 value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. 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.
We discuss a C(N)D-statement, consisting of the known and elaborating in decades C(N)D-1 statement that can be and should be interpreted as quantitative statement of approximation theory and computational mathematics, which, in common with new prolongations of both C(N)D-2 and C(N)D-3, is suggested as a natural theoretical and computational scheme of further numerical analysis development.
