hi robert,

I seem to remember that a typical non-public measurement is a one-off, and as such the data volume collected and stored is likely to be relatiely low. interesting

There is an old (late 2016) labs post worth referring to for this discussion [1]. In 2020 there was a survey of the users of private measurements [2], which was intended to get feedback on their actual use-cases. I seem to recall a very small set of respondents from an already small set of surveyees. The results are probably lost in the ether. I feel there's an aspect of the broader question that is rarely touched upon in these discussions: would user behaviour actually change if non-public measurements went away? I'm never sure how many use-cases are truly secret. Cheers, S.

I don't have the numbers readily available to me at this moment, but we can certainly dig up recent statistics about this. i did not intend to create a lot of work for you. but, as a measurement person, i am a bit fond of basing decisions on facts.
