I am saying it seems to me that all of those classifications are subjective. At least it is an attempt at being more scientific than the simple "they stopped playing here and started playing here" breakdowns I see over the summer. As for the link, I mean that it is simple to try to put a framework of of technical terms on top of highly subjective and non testable material. I WILL say this is based on better criteria than "Planar Analysis" though. Like I originally wrote, I might be the only one.
