Do you recall if you looked at the parallel results or the serially
executed ones?

I imagine that the parallel ones will have much more noise since we
run the tests up to 20 at a time. I imagine probably none, or at most
not many of the animals have enough CPU cores not to be context
switching a lot during those the parallel runs.  I thought the serial
ones would be better but didn't have an idea of they'd be good enough
to be useful.
