Degreeing a camshaft is ALL 100% grammar school geometry. Every single bit of it. I say that not trying to call you stupid......just the opposite. You're asking questions and you've realized you need to put the brakes on a little. That's good. I promise you an whiz bang 7th grader could make us all look like idiots and probably do it in five minutes. Adult minds kinda go downhill kinda quick after they get outta that "soak it up like a sponge" stage. lol
