I seriously think one thing missed besides fat/muscle %ages is bone mass. Not everyone has the same bone density, and BMI tables are probably based on a median of this range if not possibly some pathetically low mean that results from near osteoporotic individuals being included. I've had half a dozen incidents in which I SHOULD have broken bones (or skull) and didn't thanks to my tougher than average skeleton. at the same time the BMI charts will have me looking anorexic if I even get as low as 200lbs let alone my recommended 180 for being 6' tall. and don't get me started on what the army recruitment officer said when he took my measurements...
