First review round: 20.7 weeks. Overall rating: 3 (good).
The reviewers were not particularly helpful (note: it might be due to sheer chance in reviewer selection this one time, and not reflecting the general quality of reviewers for this journal). The positive review was basically a single paragraph to the effect of "this is a great paper worth publishing". The negative review criticized my draft for presumably failing to address alternative theories x, y, z, all of which I had actually discussed and explicitly refuted in the draft. Luckily the editor was quite reasonable, giving me an opportunity to respond to the negative review, and accepted the draft upon relatively minor revisions.
