He may also be on a VMNG300, that's the sort of flat lining of the avg latency i see now that i got my VMNG300 the other day, still, your average latency is pretty good compared to a lot of other people, infact, yours is quite far above a lot that ive seen.
You could try swapping upstreams, its possible the fluctuations in minimum latency are utilisation based.
