No, one should not then rotate-move the tractor when going in between inner, and outer points of the arc of protractor.
Only initially, if the protractor itself is grossly off the mark. If one cannot trace the Arc perfectly, one could possibly have the Protractor positioned slightly incorrectly.
One can then move the protractor, but then must start all over again with the overhang adjustment.
I think I have this right. Mark
