Re: 10 a.m.

FWIW, for the sake of understanding where we are, I did a small calculation of the available meeting time for the last few meetings, and thought it would be interesting to share.

The number to watch for is the session hours, i.e., time that we’re in regular IETF meetings. That time doesn’t include breaks, lunches, Sunday events, etc. Those session hours get used in different ways, sometimes we break them into shorter sessions, sometimes it is used for 8 parallel WG sessions, sometimes it is used for 1 joint plenary meeting, etc.

But of course, us individuals do have other things beyond the regular IETF meetings, say design team or IESG or other side meetings, may not attend all sessions (shock!) and so on.

The data is presented without any particular conclusion. I’ll just point out that we can independently adjust:

* length of day, implying longer or shorter full days (incl. side things)
* timing within the days, start at 9 or 10
* parallelism, i.e., number of tracks that will impact conflicts but also our capacity to host meetings that the WGs have requested
* number of plenaries (with the recent trend being 1 plenary) which affects joint vs. WG time split

Here’s the data on available session hours. (Disclaimer: there’s always the danger of me having miscounted somewhere.)

session hours		38.5

95:

96:

I also counted how many WG meetings and meeting hours there were. So for instance, if we had 10 sessions and each one of them was 2 hours long and had eight fully occupied tracks, that would be 10*2*8 = 160 hours. Again, as I just did a quick count, I could have missed something or miscalculated somewhere. And I didn’t change the counting due to cancellations.
