Wikidata - Index Information - not trustworthy because stable while query results show increase

[annainfo]

The situation is worse than described at #177 "Wikidata - Index Information - No such file or directory NO_DATE", because the data itself doesn't match the query results.

On 2025-10-18 and 2025-10-19 a query on millions of triples each triple containing external ids and the items instances of the class human (P31=Q5), was executed, the results recorded and the backend information recorded. The results showed an increase in several of the ID quantities but the backend information showed exactly the same data, namely:

The Wikidata instance is updated continuously while running and rebuilt fully periodically. The changes in the query results that you observed probably result from the continuous updates which also don't update the index statistics. The statistics are update when the index is rebuilt.
