Probably whether you hear about it depends on if your GP buys into the idea or not. For what it is worth, pretty much what the charts say for height and weight are what it is. The charts fit typical people.
If you are a BIG 10 college wrestler in the 184# class, the chart isn't gonna work. Really it isn't going to work for anybody that is heavily muscled with a very low body fat percentage... because you are gonna have weight, but that weight isn't blubber... the charts are assuming an average muscle/body fat ratio.
