I'm not sure anyone has said speed perfection is the sole goal. Obviously, taking that approach would lead to problems elsewhere, most of which would mask any benefit of perfect speed.
CD = perfection? That's a whole different topic itself, but I get your intent.
We have this tiny diamond, at times wiggly back and forth and up and down at some pretty high frequencies. Assuming that the cartridge is good enough to not skip even in the slightest, that has to have some effect on something, IMO. Those of us who use the mylar belts have heard remarkable improvements with different versions of the mylar streamers and, most notably, with Paul's latest trick of etching away the metal to expose the textured side of the mylar. Something is going on.
