Thx for these. Look like a pretty good summary.

For those who might want to find these meeting materials in future 
without saving this specific URL, interim meetings are linked off the 
data tracker IETF proceedings page:
https://www.ietf.org/how/meetings/interim/

> Please send any corrections or improvements.
During Jonathan's slides, there was a conversation that seems to be 
completely missing where Greg asked for SCE scenarios to not just show 
experiments as selected individual time series that could be "cherry 
picked", but to usually give results over a range of realistic link 
rates and RTTs and a range of traffic scenarios. Also there was a 
request to present summary "figures of merit" e.g. queue delay, 
utilization, rate ratio, packet drop, ECN marking, normalized flow 
completion time, etc. Also to show "whiskers", e.g. 99-%ile as well as 
mean, across a number of experiment runs.

(The conversation started by audio, then continued on the chat). Time 
series are useful to dig into particular anomalous behaviours, but not 
really suitable for checking the operating range or to compare solutions 
over a range of scenarios. Higher percentile figures are essential for 
queue delay to determine how a real-time app would cope.

Thank you.
And the chat log hopefully?

Now I've seen some hints at the conversation I couldn't hear during the 
chairs slides (audio problems), I'll start following-up on the tsvwg list.

Cheers
