Finally identifying a couple of chapters I could just cut entirely has certainly helped progress — it’s easier to increase a percentage by lowering the denominator!
I’ve done a lot more reorganization than usual in this rewrite; the plot just seemed to work better with a different sequence of chapters. I’ve also changed my point-of-view character a good bit, and that basically involves an entire rewrite of the scene.
Still hoping to be done with the draft by the end of April. Seems like a bit of a stretch, though.
