Well, it's not great at outlier heights. It's been pretty contentious for a few years, there is a new model that they say is more accurate. Allow taller people more weight and shorter people less. But also, this person is super dumb. It's height squared, not 2 x height, so the percentage isn't constant... that's the whole problem... Are poor people generally a lot shorter? Like is that just a thing I've never noticed? Do I need to start checking my height privilege?
