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.
Random orientations and uniform distributions of rock-forming minerals increase their resistance to pressure under load; the pyramidal fragments into which they are eventually shattered are of regular shape and relatively small, like the biotite granodiorites tested here. Definite orientations of the minerals and their cleavage planes, as in the biotite granites, shorten and lower their resistance to pressure, yielding large, irregular “pyramids.”
