> The problem with velocity isn’t poor metrics, the problem with velocity is it’s trying to measure a meaningless quantity. that's exactly right, it's taking 2 dimensions (estimate and fitness of estimate) and quashing it down into 1 dimension, where you necessarily lose information. It's a point in that it's an abstract idea that can represent an atom or a universe. It's not useful for anything outside of the abstract.
