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.)

89:
sessions                21
session hours           38.5

90:
sessions                18
session hours           35.5

91:
sessions                18
session hours           35.5

92:
sessions                18
session hours           35.0

93:
sessions                19
session hours           36.0

94:
sessions                16
session hours           33.0

95:
sessions                18
session hours           33.0

96:
sessions                17
session hours           33.0

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.

89:
WG meetings             140
WG meeting hours        256.0

90:

92:

93:
