my own experience is the misinterpretation of the above properties in
traceroute is pathological to the point of making it useless in the
hands of novices...
you shouldn't be looking for jitter in traceroute, because it's not
measuring the forwarding plane it's measuring the control plane.
intermediate loss is mostly meaningless, unless it cascades, in which
case it may have meaning but maybe not.
