And without proper preparation that time increases.
I'd say 80% of my script is outlined by now. I feel I'm missing some logical connecting scenes and only one of my main characters gets all the fun stuff. Work and procrastination make it hard to beat it out on a regular basis but bit by bit I'm fleshing it out.
I hope my UCLA class helps me out with creating a fully fleshed out script by the time it's over.
