I love the numbers but they don't tell me the difference between "just right", "under built", and "overbuilt" not to mention the difficulty in understanding them. Try comparing such disparate materials as Royalex, FRP, Polycarbonate and Polyethylene and the numbers don't make a lot of sense without expected loads. A tough problem where publication could cause more confusion than good.
