Does this prove David Vizard's 128 lsa formula ?

I have not read this thread, but.... to my knowledge, DV's formula usually arrives at a number with a tighter lsa than most.
I have a (old!) Cam Dynamics sbc solid roller I wanted to use. Unfortunately i couldn't in my app, (5.7 rod, 406) cause the rod hit the camshaft in a couple spots. (NOT the cams fault, long rod 400 usually needs a smaller base circle cam.)
Upshot of this post is.... the cam was ground on a 104 lsa. I've never seen one tighter. I bet it would have sounded nasty at idle!
