That is GREAT, lets see if Richard agrees with you on cyclic symmetry.
BUT, perhaps that cyclic error on the last 10 degree sector was related the the RHINO bug.
Did you try a run on your Parasolid 10 degree sector with cyclic, just to make sure our cyclic problem is not RHINO bug related 
I the meantime I used your Quarter model and made the plastic ~10 times ‘softer’ so the coin diameter would increase due to less ram force which causes less flexing in the die plates.
Ideally I want a uniform 0.002" think plastic coin.
Here are the dimensions of your run in inches at various points:
And with my run with 10x ‘softer’ plastic (this got an extra 1/2" radius on the coin and very close to 0.002" thick almost everwhere 
).
Yeah, I think that horse was won the race
