All right, as it's my first time, I'm jumping the gun today with a test run. So far, given that this is supposed to be the easy period, I'm not doing so hot: 744 words in more than an hour. Once I no longer have to make conscious effort to keep myself from going back and correcting my word choice twice a paragraph, I might have more of a handle on it, though.
EDIT: Two and a half hours, all told. I can live with that.
