Even when the process the man page is describing is non-deterministic?
So you want man pages that lie?

You seem to have some pre-conceived and incorrect notions, together
with a don't-confuse-me-with-the-facts attitude. You've hit the Daily

you'll most likely be happier in the long run. No guarantees, of
course.
