Like I said earlier, in stuff like this it's not hard mathematics that reveal the true state of affairs: UBW editing progress: 52% (yet 10.5 of 13 days finished). It's good to keep in mind it's rather the total length of the source than a number of days. The days might contain different amounts of text, after all.

It looks good so far. If things continue like this and they all have as much guts as the editor(s), it wouldn't be unreasonable to hope for a release in a month or so.
