"But there's a point where extra effort makes the work less good."
This happens frequently in mixing and mastering audio tracks. You pile up incremental changes that all seemed good at the time. Then you go back and listen to a recording from 20 revisions ago and it sounds better than your current "best" effort.
Sometimes that is because you need 60 more revisions to make it good - though you may have to go back to the start several times to figure out which are good.
