lol. It depends on the page and how familiar I am with it already. My first pass through I was doing probably somewhere around 10 mins per page for the dense ones, and closer to 5 for the less dense ones. Second time through its about 5 mins per page on average, with some of the quicker ones in probably about 2. Of course, this assumes that I don't get distracted every other page as I'm doing right now....
(time to go back to first aid for me)
