Looked at it some more tonight.

It’s the worst on the opening side. At max lift not too bad and gets worse on the closing side but not as bad as the opening side. Base has no marks.

The worst groove is 0.0008 inches - so almost a thousandths. I actually thought it would be worse.

The worst ones have pretty significant burrs.
