Ok,
I dug out my dial indicator from my past life as a machinist.
With the indicator on top of the platter, I got run out from .0005 in 2 spots then it jumped up to .001 in one spot.

On the side of the platter I got less than .00003 circular run out.

Not sure what VPI uses for their flatness tolerance, but I think it should be better.

Wonder if Acrylic warps over time?
