Erratum to the article “Evaluation of Possible Mechanical Property Improvement for Alloy of the Al–Fe–Si–Mn System by Equal-Channel Angular Pressing,” by A. B. Naizabekov and V. A. Andreyashchenko, Vol. 57, Nos. 1–2, pp. 159–163, May, 2013.

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.
