I'm measuring five circles that are equally spaced on the OD of a circular part. The first hole is directly in front of the operator and they're programmed counterclockwise. All holes are verified at .344 with pin gauges but the CMM is giving me very out-of-whack measurements. I adjusted the workplanes to be correct to the best of my knowledge (closest to nominal) but some are still very far from their actual size. This is my first program in which i've had to change work planes so I wouldn't be surprised if this is the issue.
Code is below (added spaces for readability):

Some of the dimensions have Max & Mins that are all over the place as well. Anyone have any insight on this?
