What are you even getting at? Are you saying that people misreported "uninterrupted work time" while in the office? Because I know if a coworker asks me a question in the middle of the day, it definitely isn't uninterrupted work time.

I’d put money on it being the case everywhere.

I mean not really. I have 2 one hour meetings per week. One is a 1on1 with my boss and one is with my team. That is about perfect

That just means you already managed to not have those meetings that the average company is apparently wasting time on, not that those meetings you already don't have are beneficial.

I have meetings with my research group and I look forward to them!
