I’m pretty sure the science says it’s more like 20-30. I know personally, if I try to work more than about 40-ish hours in a week, the time comes out of the following week without me even trying. A task that took two hours in a 45-hour “crunch” week will end up taking three when I don’t have to crunch. And if I keep up the crunch for too long, I start making a lot of mistakes.
