Every time I see manager with 5 people I know it will be daily 30m standups, friday “summary” meeting, weekly 1:1 and other nok work related activities. If team of 5 people need a babysitter fulltime it means there are no adults on that group.

No, 5 is about ideal. If you are micromanaging with that many people on your team then you are neglecting other aspects of being a manager. More than about 7 and you start being unavailable to your team when they need you, and won't have time to do the planning and process tasks.

Matches also my experience if they were overseeing only one small team.
