Teaching the Mount Permanent Error Memory

I was just perusing the updated instruction manual for the keypad and
re-reading the section in the manual concerning permanent error memory
and how to train the servos (page 53 - tools menu).

It states that besides training the PEM manually with crosshair
eyepiece (who does that anymore, anyway?) you can use an ST-4 or STV to
autotrain the mount.

Is there any reason that any other autoguiding system shouldn't be able
to do the same thing? Any autoguiding system (PHD, MaximDL, etc) will
send corrections to the servos to keep the mount tracking accurately,
so will the mount's controller remember the corrections and record the
PEM?

Thanks,

Hunter
