Im sorry I should have clarified you cant calculate all the data points given on a cam card. And I trust a degree wheel to be absolute.

This ^^^^

My point wasn't to prove you wrong. It was to show you don't have to have the cam events printed FOR you. With just the cam centerline, & advertised duration, you can derive the theoretical cam events.
I've never tried to derive the events from the @ 0.050" , but it can probably be done as well.

Not exactly true but …..
Most calculations are done with a know advertised lift point of let’s just say @ .006. If you start running through a Comp Cam catalog, only certain cams are advertised in this way while others are at different points.
Now travel onto Crane Cams, Howard’s, etc….
You’ll find the same thing.
