I'd much prefer mid afternoon meetings. I can wake up, get to work, minimal interuptions and then be confident of where I'm at by mid afternoon.
If I could start each day with 2-3 short meetings then have the rest of the day available to get something actionable done, both me and my employer would be much better off.
Different people have different preferences, getting a meeting cadence that works best for the majority of the team is going to result in the best results possible.
The set of all people in the graph meet, and the topics are handled by largest group getting info and being done with the exchange.
Which also means, yes, half the group can get up mid meeting, and the remainder can fall apart into two seperat meetings.
