I think this is a valid critique, but I'm not sure what the alternative would be. Probably wise to show some humility and not treat a list as perfectly ordered gospel, but treat it more as a general guide to show relative placement of a variety of players playing over a variety levels. It will always be more art than science. Being an aggregator of information from a variety of sources, blending that with skills, playing hunches, putting yourself out there. These are all skills.
