I got feedback from 12 people, which I'm guessing is about a quarter of the audience. I had a number of people who either didn't know what to expect, or found the math a little hard. The ratings averaged out to 3.67/5. I have no idea how people tend to rate these things. I'm guessing that is at the "improvement needed" end of the scale, which is not entirely surprising considering that it was the first talk that I ever did on this scale. However I'd have liked to do better than that.
Does anyone have any idea how I should be scaling my expectations?
