I think maybe we should completely switch to admitting this. Every extra second you sit in the (home)office adds to productivity, just not necessarily converting into market values, that can be inflated with hype. Also longer hours is not necessarily safe or sustainable.

We only wish more time != more productivity because it's inconvenient in multiple ways if it were. We imagine a multiplier in there to balance the equation, such factor that can completely negate production, using mere anecdotal experiences as proofs.

Maybe that's not scientific, maybe time spent very closely match productivity, and maybe production as well as productivity need external, artificial regulations.
