My writer brehs, I've always wondered this, but never really heard anyone talk about it in a concrete way.
On an average to good day, how many pages can you write?
What's the most you've ever written that was actually good or useable after you came back the next day and read it again?
I tend to write sporadically, not touching FD for days, even a week or two, but always thinking about the script and only feeling like I need to write once I've "watched" the scene in my head 5 or 6 times. Then I'll sit for an hour or two and bang out 7 or 8 pages.
