Yeah, that's kinda why I said just go with whatever feels right for you.
For me, I don't always come back to my scripts often enough, so I need to know exactly what direction I was heading in. That's kinda why I keep my as detailed as I can be. I work alone, so this is really my best method.
But, as you said, some can keep it bare-boned and it works for them. It's really just keeping to to where you can understand it if you've been away from it for a while and aren't actively working on it.
