I have been writing a novel using open source tools and also openly at GitHub http://jj.github.io/hoborg. As an added value, I have data on each and every writing session: I know how many words were writing. I'm running some analysis on it, and found that writing session word deltas (number of words written in each writing session) follow a power law. Data is already shared in the GitHub repo but I'll share more with my conclusions, but it would be interesting to have some data to compare. Does anybody know if there's some data on this? Has anybody kept a log of, for instance, how many words were written in each session?
