Bmi is a terrible scale for everyone and needs to be abolished.
It honestly works fine for most people. I've found that the people who are usually most vehemently against it are fat people who are offended at being labelled obese/overweight. The true outliers, who are rare, like tall people and bodybuilders don't really seem to care. There are of course better scales, but most of them aren't as measure and most doctors can tell you're an outlier and it wont' work for you anyway by just looking.
I'm 170 with 15% body fat at 5'9.5" and a 31 inch waist. According to bmi, I'm at 24.7 on a scale where 25 is the lower edge of over weight. That's not a good scale.
It's a little self-conscious you feel the need to specify inaccurate stats.
