This isn't an answer but it's geeky interesting.
We built algorithms on this, and it drives some of the durability info you see on the DN site. The mold's specific physical attributes, the method of wear for a particular plastic, and the wear interaction between mold features and plastic all play into a disc's durability rating. That's as specific as I can get with the formulas
Our system is smart enough to know that a Pro Boss is among the most relatively rapidly-wearing discs because of its long wing, lack of bead/notch, and propensity of Pro plastic to bend its wing on a hit. By the same token, DX plastic shreds more than slicing or bending, so the wear-resistant bead, wing, and nose features of a DX Roc make it about equally gradual-wearing as the Pro Boss. If we exposed a per-hit durability rating, the DX Roc would win hard over the Pro Boss.
AFAIK it's the first mathematical logic in the industry that knows about stuff like notches, beads, bending, shredding, etc. That was a super nerdy weekend.
