Yep, that's what I thought too. I contrast it with an accident and emergency consultant I know in the UK. He actually is grinding 70 hours a week and not compensated for it. He works long hours because there aren't enough staff to cover the reality of what's needed.

I do this several times a year. It’s a lot of fun. You basically camp with colleagues and get a lot of collaborative work done. Then you detach and do your deep thinking. The problem is top performers eventually gain an ego and stop attending, and then it just turns into pathetic signaling.
