The amount of time that relevant meaningful information is shared in a scheduled meeting of 3 or more people. This is inversely proportional to the amount of time scheduled for the meeting not to exceed the time of a microvisit.
The larger and longer the meeting the less the relevant information is shared. Large meetings requires little or no microthought.
While sitting an an all employee meeting, I had a microthought of what I could be working at right now. Then I went back to thinking about what I am going to do this weekend.
