There are a couple of short (a few seconds only) edits where I just zoned out thinking about something, but the big breaks are clearly labelled. Also, check out the clock at the bottom right corner!

I started this at about 14:00 and finished at about 01:30, so about eleven to twelve hours wall clock time. And yes, if I hadn't been doing the recording I'd have given up and gone to bed. Also I, er, had to get up at 07:00 the next morning to go hiking.
