Are you going to max lift and then going down .050 on each side and taking your measurements?
If so, on some lobes you can introduce an error there.
What I do is zero the dial indicator on the base circle and for your lobe I would go up to .250 lift on the opening side and take a reading. Then go up to max lift and then on the closing side when you get to .250 and take a reading.
Doing that means you are exactly at max lift between the average of those two numbers.
