1) It shows "series 2" for the drill downs rather than upload/download/idle.

2) I am not big on averages, period. showing min/median/max on the bar chart
is more satisfying to me, (see relevant netperf-wrapper plottype), but I know
that too is confusing to users.

Saying "average bloat" is sort of like saying this drug only kills 2%
of people on average - it might be accurate statistically (except for
missing a long term trendline and not coping with different RTTs
well), but it does tend to matter to those it kills.

I know tons of people like plain old bar charts, but...

3) I like how this drilldown and the previous detailed graphs shows
the queues building over the course of the test. This lends intuition
to the problem (and shows the trendline in particular)

Perhaps something that would be interesting would be for the drill
down to instead
swap between graphs over an interval (every few seconds), then stop on the
worst one after 20 seconds....

going back to the first screen of the test actually running:

4) The radar ping plot is boring after the test starts, and on a small
laptop the bufferbloat
"tach" is invisible. I would remove the radar ping plot after the test
starts and stick the
bloat tach there instead.

Aint I demanding?

5) (this is still marvellous work and deepest gratitude, and so on,
and thanks for playing with us)

6) we are so losing on inbound at the moment.

7) I hope to add some tests to the finally renamed flent (formerly
netperf-wrapper) that will more closely duplicate your tests. In
particular, I want to add support for many different remote servers to
all the basic tests. You have clearly pointed out that we need to
tackle that,  and see items 5, and 6...

Are you settled on 16/6 for the basic "cable" test, in particular?
