Depends on how strict you mean by "strict distance relationship between
the arm pivot and the spindle center?" I have a separate 15lb armpod
and I tested the theory that alleged movement. I aligned my cartridge
according to the Mint lp protractor, used the set up for x amount of time and
then put the Mint back on: no movement that I could see with that tool. If
someone wants to argue that with better tools I would be able to detect the
movement, then fine. But that's a moot point as far as I'm concerned. IMO, the
weight of the pod and the type of coupling feet (spikes in my case) one uses
should prevent any gross movements. I have a lighter 8lb pod that doesn't
appear to move either, but I never tested that one.
