Very interesting article. Just one note: I have no idea how much 80 centimeters is. If one’s publishing an article for consumption in the U.S., it’s rather obtuse to use metric measurements alone. I suppose some think that makes it sound all scientific, but the fact is, it isn’t the common system here and any benefit to it disappeared with the advent of the pocket calculator.
