Cylinder measurement variance

I'm measuring a cylinder using an auto cylinder and 3 rows of points. I'm reporting cylindricity.
Tell me why the hit points look like this if the feature is machined with no interrupted cuts?

Is your probe dirty? Worn? Part moving? Module bad? Head bad? Probe force correct?

Scan a calibrated ring gage and see if you see the same variation.
