Does this prove David Vizard's 128 lsa formula ?

Yes and no. It really doesn’t matter - Why?

You have seen here, read everywhere and been told over and over again to do what????

Degree your cam! Then you know it’s right.

My MP .590 needed a 1* adjustment. Oddly enough, that was the only cam key I had on hand.
I get that as long as it's degree'd it should be fine... i just worry about everything and being 6* off was just bothering me, wanted to know if it is a known thing that happens is all :)
