Check My Cam Degreeing

When degreeing a cam, I prefer to use the .050" lift numbers as if you try to use the 'advertised' numbers or .001", .002" etc it can be inaccurate as when the lifter begins to lift, it is moving slower and it may be at the same lift for a few degrees...

I take measurements at .001", .010", .050", .100", .150", .200", .250", .300", .350", .400" and then try to get a number at max lift, but that also is difficult as the cam is slowing down and changing directions and you may have max lift for a few degrees - sometimes 4° - 10° before it starts to move down... I record the 'range' of degrees when it reaches max lift and then compare the calculated center line for that lobe to that number using the lift ranges from: 050", .100", .150", .200", .250", .300", .350"... I also compare the calculated center line from each of those lifts to see if they come out the same to tell how accurate my numbers are....
