I agree with this, you will almost always get better results by simply undoing and rewording you prompt vs trying to coerce it to fix something it already did.
Most of the time when I do use it, I almost always use just a couple prompts before starting a completely new one because it just falls off a cliff in terms of reliability after the first couple messages. At that point you're better off fixing it yourself than trying to get it to do it a way you'll accept.
