I must have missed this e-mail previously, sorry about the slow response.
John Baldwin pointed me at it wondering why I hadn't answered, and that's
why :-).

Is the number of mbufs lost proportional to total run time since the
start, or number of runs since start?  I.e., if you shorten 60 seconds to
6 seconds but sample at the same rate, what impact does that have on the
measured leakage?
