motor arm

[magnoan]

I was wondering if matter where on the motor arm (SG2100) to mount my dish ( see attached pic) Should it be mounted even with the bottom of the arm or in the middle of the arm or as far up the arm as I can go? Does anyone know if it matters is there a preferred spot on the motor arm where I should mount it. Thanks in Advance

Pole is plumb by the way…..

I would have thought that as high up as possible without causing anything to bind, might be the way to go.
However, Chuck seems to have come to a different conclusion in this thread:
