>ICs tend to stick around and over run meetings, while managers tend to leave meetings on time.

That makes 200% sense. A couple or more ICs tend to want to stick around to go off topic or drill down on some thing if they don't have a conflict. People who aren't expressly relevant to that or have a conflict drop at that time.

You're basically seeing the post-meeting hall conversation of the ICs in your data.

Additionally, most meetings are worthless drivel from an IC perspective. The off-topic/drilldown is usually when ICs actually discuss topics relevant to them and get into a level of detail on issues that actually helps further the project.

Not to mention that managers are way more likely to have back-to-back meetings.
