How? Azimuth in the context of a stylus is defined as a vertical centre line through it, looking at the front of it, and correct setting of Azimuth is so it is at a right angle to the record surface, or have I misunderstood something here?

Or is it that due to the geometry of an arm tracking across the record the angle of the head shell changes very slightly, so it may be spot in the centre of a LP but slightly out at the outer and inner edges? If this is the case then the difference to the Azimuth must be minute, and with a modern cut stylus I would have thought likely to have minimal significance?
