Degreeing a Cam, or not.....
If you are going to measure at the retainer, use the same lift point on both sides if it's a symmetrical lobe. The math with work out the same. You can pick .050, .075, .050 off max lift, doesn't matter, the math will get you the centerline number.
I won't bother moving anything for the 1* it is off. Waste of time.
