The 2 volume aristotle is around 2500 pages (so 2.5x schattenfroh) and the text is smaller and denser, so I'm only able to do about 75% the rate. Assuming I take one rest day a week, I'll need to read about 33 pages a day to hit the goal. This is on the very upper end of my current fitness level with not a lot of room for error, so it will be a challenge.
