That's evil! LOL Has anyone ever made a chart of Butcher's average pages per chapter length and seen whether it has gone up or down?
If I did that someone would suggest that it wasn't good enough. To be truly accurate we would need to compare the average number of words per chapter Jim has used over the past five or six books. Plus, it wouldn't hurt to know the highest number of words in a chapter Jim has used per book and see if that number has changed significantly over time. We could also do a character count per chapter, and divide that by the number of words per chapter to see if Jim's vocabulary for Harry and the other characters, plus the description of people, things, the environment, events and emotions have become more complex, meaning Jim is using bigger words, not just more of them. Of course, some people might think that last suggestion is a bit too much, but aren't you a little bit curious to find out?
