In less than two days I've cranked out 16 pages of manual. It's a short thing on installing and configuring a product, but IIRC the "normal" time allotted for documentation is 4 pages/day.
This, despite a killer pain in my left arm that may prevent me from playing guitar at my concert at Westercon in two weeks. (I see my internist Monday. Dr. Jane can't figure out what's screwing it up.)
