I like this system. Having the outline allowed me to flow from one scene to the next in a logical and consistent manner, and I drafted it in four days rather than the month that something like this would've taken me in the past when I was pantsing.
Of course, it came in 6% over the wordcount limit (6400 words on a 6000-word limit), but I can fix that in post. It also needs a better ending line, which I can also fix in post. And, of course, a title, which will come to me eventually.
