Charles, I have wondered for quite some time as to how a system such as this works. In years passed I was tested every three months for BMI that involved percent body fat relative to muscle, etc etc. This is a program I volunteered for some time ago and is sponsored by one of the hospitals in our city. In the early days of this program, a "standard" method of calculating body fat was used; i.e. calipers. I'm told there is a significant improvement when using the scales and the medical practitioners now use only this method. Quite impressive and much less time consuming. This means you get the bad news and the lecture even sooner.
