I realize that you were directing that post at snowolf but I am certified through AASI-East and have been a member for 10years r so. My guess is that he saw that your focus on high edge angled turns were going to hold you back in the long run. Often(myself included) the more we learn to make high edge angle turns, the more we lose the ability to ride a low edge angle. Now, low edge angles are important for riding trees, bumps, and boxes/rails so its important to develop that ability so it doesn't hold you back down the road.
Out of curiosity, who was your examiner?
