"azimuth could be off
overhang could be wrong
vta could be off"
All of the above are possibly true but would any of those errors generate an effective anti-skating force? Overhang and VTA might effect the magnitude of the skating force by a little, because such errors would marginally effect the size or angle of the contact surfaces between stylus and groove walls, thereby affecting the friction force that generates skating, and very incorrect azimuth would cause problems of its own.
