Indeed, and more than likely dead useless.  The only benchmark that
really counts is one's live application, which is probably not
update-only and probably has a fairly non-random update pattern too.

What people have been trying to point out to you is that you can
certainly measure *something* with a benchmark test that has no thought
behind it, but it's not clear whether the numbers you come up with will
have any real-world value.
