I literally have no idea what this rating scheme is about.Camphor Burl has a rating of 1800, which is between monkeypod and Olive. That might mean more choices in pad rolling (completely debatable). Is it accurate to say most monkeypod owners preferr the Auteur Lambskin or some type of solid lambskin? I could be wrong.
I listen with my ears, not with graphs and ratings, and I'm fairly sure subjective preferences can't be quantified and classified in the way you're seeking to do.
