No, my thought was possibly a number got transcribed wrong or digits
kicked or something more along those lines.  Or something different
happened during that test that wasn't happening during the other cached
tests.  There's an obvious trend with the cached tests, and that one
test doesn't follow it, so I just wanted to point it out.
