One thing that happens when you take a story from pitch to a step outline is you notice all the places that you've shown passage of time. I'm reading a treatment that says "A and B drop by regularly," and my note to the writer is, "regularly doesn't happen in the movies." Regularly usually means once. Sometimes it means a montage, but usually it means one scene where it's clear that the same thing has been going on regularly.
Watch out for "regularly" and "over the course of the next few weeks" and other things you cannot shoot in a movie. It's okay to put them in your pitch, but be aware that they're hand-waving and they'll have to come out later.
