No, if a diver goes to 61, then 62, then ... etc (but not past 100) they are going to learn more they will on the deep dive as part of AOW (seriously, look at color absorption? Compare dive computer depth readings? How the F do those make a diver safer at 100 feet?).
I don’t completely disagree with what you say but I was referring to the initial question that was referring to an instructor. Instructors acting as such must follow agency standards.
