    <thetext>run-perf-tests should report the mean instead of (in addition to?) the median

I&apos;m told I should be reporting the mean in my bugs:
https://bugs.webkit.org/show_bug.cgi?id=107337#c40

I may have been a Math major, but I plead ignorance for stats questions. :)</thetext>

We do report them. e.g.

Running Bindings/document-implementation.html (4 of 114)
DESCRIPTION: This benchmark repeatedly accesses document.implementation.
RESULT Bindings: document-implementation: Runs= 337.387461737 runs/s
median= 336.553080486 runs/s, stdev= 8.51712865431 runs/s, min= 321.659870522 runs/s, max= 347.246989122 runs/s

The mean is 337.387461737 runs/s.</thetext>

    <thetext>I see.  That was not at all obvious to me in reading the output, but perhaps it should have been.</thetext>

If it was&apos;t obvious to you, it clearly is a bug. Let&apos;s fix that.</thetext>
