I really forgot to take the camera out of the bag most of the time - peak output was 16 an hour - average about 10.
Still not sure if I enjoy doing it - though the people are great ( and so's the money !!) but I'm nowhere near as comfortable with the end product as my studio work - too much of a perfectionist I guess regardless of the little voice in my head saying 'forget the portrait' I still head that way.
It's all studio work until Christmas and then some heavy practice before 2010 'live' shows.
