Jordan, you hit it dead on. This is one of the papers I have been reading. Although Sierra has different examples and Berger cites the Sierra studies this guy goes right along with what you stated. No excerpts just a link and photo. It’s a good read to me but maybe a little boring to you. Pic is courtesy of Brian Litz.
