Sorry, but wrong again. Look back at TomB's post in this thread to see what % grade really means.

It's definitely the case that % grade is not a percent of 90°. 72% grade is equal to just under 36°. With all the talk (in another thread) about the importance of solid self-arrest skills on steeps, don't you think that another safety tip might be to be know how steep that pitch is where you might have to practice your self arrest?
|wrong dude. it's 72%. That means 72% of 90°, or 64.8°.|
