It's one way of dealing with it.

Anyway, wrt speed testing I suggest you make sure you're using CPU time
not wall time, running for a decent length of time, and then do whatever
you're doing 10 times and work out the standard error, automating the
averaging and errors so that you don't have human error in assessing
whether your number is reliable or not.
