Six days ago I began (what I thought would be) an essay on Romer-Lawrence-Windsor (more on it later). Six days later, and 48 hours of editing (Word keeps track of that), I have produced ~23,000 words. I wrote less on weekends, so it is not evenly 8 hours every day. That translates to roughly 500 words per hour. I think I need another 3 or 4 full days on this (now) article to finish writing and a few more days to get it in SSRN shape.
