I’ve been strict about being a 1x dev for a few years. On a Very Big Project a few years ago, I was proud some other team members followed suit. I did some long days to increase US cross-over but buggered off early on Fridays to make it up.
one 1.00000001× day is more productive than a 10× day followed by a burnout 0.1× day
the math don’t lie

I don’t think I ever told the client about the shorter Fridays, but I also reckon they were smart enough to pick up that the guy doing 40/hrs of code review each week never sent anything late Fridays.
