Perhaps a tangential 2 cents from me, but I'm unclear how helpful Hertz is as
a unit of measurement for the challenge of raising awareness of bufferbloat.
I suspect data networking people (whether network designers, admins, product
managers, etc) don't think of IP networks as having characteristics measured in
Hertz. And I'd imagine most ISP helpdesks wont know how to parse customer complaints
along the lines of "your service doesn't give me enough Hertz". Perhaps your tool
could also add a parenthetical 'translation' of the responsiveness and smoothness
values into something expressed in milliseconds?
cheers,
