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.
A critical analysis of literature data on the records of Elaphe sauromates in the Atyrau region of the Republic of Kazakhstan in 1857–2006 is presented. Doubtful finds of the species in the Volga-Ural interfluve and in the vicinity of the city of Atyrau require confirmation. New finds in the region in 2018 and 2021, like all reliable previous ones, were made only on the territory of the Zhylyoysky district.
