Cam degreeing. I totally don't understand.

Maybe I have just been lucky. I have built quite a few engines in my day, and I have never degreed a cam. I have never had a problem, and every engine ran great. My current 340 is probably at least 75HP over stock, and it runs really well with a 'straight up' cam in
How do you know its " Straight up?"
If you didn't degree it?
Dot to Dot doesn't mean Straight up.
Like the example I posted,
When I put it Dot to Dot it was 8 Degrees Retarded!
Most cams come with 4 Degrees of Advance built in, so in a Perfect World
Dot to Dot will be 4 Degrees Advanced from the LSA. (Ex. 110 LSA in at 106*)
Straight up means there's No Adv. Or Ret.
It's the Same number as the LSA.
with all the quality control problems,
Stack Tolerances...ect.
just lining up the dots rarely comes out right.
Sure it'll run in Most cases, But at its best or the intended use, Probably not.
