> As someone who went from working a 5-day week to a 4-day week, I feel like a 4-day week is a 'sweet spot' - I'm just as productive as I was working a 5-day week, but when I work any less than 30 hours a week (e.g. when I take a day off), my productivity always goes down.

Perhaps - but I suspect it depends on the person and the details of both job and workplace.

I spent about 6 years working a 3-day, and it went really well. However, it was more vulnerable to constant-cost outside factors like "unneeded meetings".
