I admit it: I have a problem.
Not long ago, I emailed someone an estimate on when Chapter Five would be posted (a week or two ago). At the time, the estimate was completely accurate.
Then I had to go and start adding to it. 'Oh look,' I said to myself, 'that's a great spot to add that one scene I've been meaning to fit in. And I should really expand that bit. And while I'm at it, I have a neat idea for a new scene there.'
So my old 80-pages-max estimate for Chapter Five is currently sitting at 87 pages, with a new estimate of under 100 pages. And remember that I'm not a fast writer to begin with.
However, the first half of Chapter Five is now complete, covering the Tokyo part of the trip. The Kyoto half is maybe 90% complete, give or take. (For me, the Kyoto half is more fun, though the first half is more important story-wise.)
So what I'm doing is posting Chapter 5A today (or at least submitting it for posting). Once the chapter is complete, I'll repost/replace it using the completed chapter. Hopefully, that should happen within the next couple weeks.
