Is degreeing REALLY necessary?

Hi guys- my previous thread regarding cam selection highlighted my abysmal lack of understanding regarding cam timing.
I have read on this forum and in the mag.s that one should always degree a cam before running it.

I'm somewhat reluctant to mess with changing the advance or retard of my cam, simply because I may mess something up.( I was looking at my Summit-brand degree wheel while posting and still couldn't figure out my LSA)

So my question is this- is it really necessary to degree cams in these modern days? I mean, I'm sure the cam grinders are seldom, if ever, very far off on their grinds. Has anyone recently degreed a cam and found it to be badly off? How much?

And if a cam is off by, say, two degrees-how much power or driveability would I be leaving on the table? I get the impression it wouldn't be more than 5hp/tq. Am I right?

Besides, I'm sure I'll leave more than that on the table through limited tuning ability on my carb and dist. advance curves...

Regards,
M.R.
