You're actually a great example, because you've gone through a very obvious improvement over the last 6 years -- exactly the kind of improvement exercise and diet is supposed to bring about it, from out of shape to in shape -- and yet it doesn't show up on this scale at all. If we generalize from your example, the scale seems incapable of detecting exactly the improvements it is supposed to catch.
