Since a few people asked how long it took me to do those stats: 133 characters took roughly 5 hours (some of which was fighting with Excel, which I’m not good at).
Aliettedb reports her results–172 characters took her about 2 hours. I guess she’s smarter than me. 🙂 Marshallpayne1’s results for 107 characters took 3 hours.
So if anyone was thinking about trying this, but worried it’d take too long–it’s easier than it looks. If you’ve got a ton of stories, you could limit it to only the last two years or whatever makes sense to you. I didn’t count anything in my finished drafts, for example–just published and circulating stories.
