The test above shows the stats if there was -P , -L & --rate, because
under these conditions the necessary data was collected, so they can be
computed. Thus the output in the documentation assumes that one of these
was used. I nearly always use "-P 1".
Note that the documentation is not really precise, "will look similar to",
so there is no commitment.
If you feel like removing the stddev line from the doc because it is not
there with usual options, fine with me.
