Except it's NOT a jitter metric. It is a latency under load metric primarily aime
at testing in-band (http 2.0 or quic) AQM latency. Most of our other tests
to date have a tendency to favor FQ measurements. 

Certainly jitter can be pulled out of detailed measurements using some
of the proposed methodologies. See the rpm at lists.bufferbloat.net list
an archives for more details.

We have a regular meeting on implementations and new data
at 10AM PDT tuesdays if anyone would like to join.
