"mean daily users" is the mean of what?
https://metrics.torproject.org/users.html#direct-users-table lists Iran at 24200 mean daily users. But https://metrics.torproject.org/users.html?graph=direct-users&country=ir#direct-users shows a number more like 40k or more.
So what time period is it taking the mean over?
Maybe it should be a shorter time period.
