That’s admittedly a great point. I think my record was either 12 or 16 hours a day, but it’s incredibly exceptional. Anything above 8 hours of actual, productive work is the result of high enjoyment and focus or a deadline panic mode that’s not sustainable. I think setting 6 hours as a baseline and being able to tweak from there would be ideal, but setting an expectation of over 8 hours as a tradeoff for fewer days is harmful imo.
