Hi Doug,
if the arm-post is tilted relative to the platter (not 90 deg.), the azimuth keeps on changing from beginning to the end of the record, aye.
Why? Because the bearing (most usually has a ~ 20 deg. off-set relative to the straight axis of the arm). One thing I learned real fast when using some cheap arm (Pro-Ject 9c) with a sloppy arm collar for setting VTA.
Go figure... and Dertonarm should concede being in touch those Egyptian geometrists :-)
