As a corollary, I find that any work performed after 10 hours in a day will require revisitation. When one gets that brain-weary, one ceases to be productive, in 95+% of cases.
That, at least, has been my experience.

Depends. You’re right - beyond a certain point there are diminishing returns; but I generally find I write better code late at night when there fewer distractions.
And sometimes, those diminishing returns work for the benefit of those who build bureaucratic mazes (and obfuscated code) - that systemically corrupt games are run within.
