Here is my breakdown of the top-10-by-usage qualifier predicates:
From https://tools.wmflabs.org/sqid/#/browse?type=properties as of 13 July 2018
Label (ID) statements qualifiers

Hi Peter,
of the top ten qualifier properties by usage I find maybe just the stated as (P1932) as contextual one.
Please, can You send examples of them of contextual and additive?

That does the trick, thanks.
I was trying to see how many uses of Wikidata qualifiers are contextual (i.e., give information about in which context the statement is valid) and which were additive (i.e., do not limit where the statement is valid).
Of the top ten qualifier properties by usage, five are contextual, three are additive, and one does not carry world information. The last can be considered to be contextual, but also might be considered to not carry world information.

I'm trying to get a good estimate of how often which qualifier predicate is used.
The obvious query times out, as expected, so I was trying to find a list of predicates that are used as qualifiers so that I can craft a query for each of them. There is https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.wikid... but that can't be trusted as it doesn't include start time (P580) or end time (P582) which I expect to be the most common qualifier predicates.
So, I'm stumped. Any suggestions?

might help you.
