A couple of nitpicks.

OK, out of several choices, you selected "iterations".

Since "iterations" is the term, be consistent and do not mix it with
"loops". Who knows may be the "loops" term will be used for something
else in the future. Use something like this:
"--iterations count Number of measurement iterations (requires '
--interval')"

Please, name variables in a consistent manner, this should really be
something like 'int iters = 0'. Or may be 'done_iters', or something.
But not "loops".

If you used term "count", you could have consistent long and short
option names, like '--count / -c'. I find '--iterations / -t' to be
inconsistent, and harder to remember the short option, because I think
about time, not "iterations" when I see -t.
