Kevin, Mike is right that you're not so "off" at all. The zigzags you may be worried about are actually your vibrato, and it appears to be nicely centered around the pitch. Without those zigzags, you would sound like a dial tone.

It's so easy to pitch-correct all the personality out of a vocal, and your vocals are always the star of your recordings, to me.

I only use pitch correction as a "tweak"...just to rein in the overly wild moments without having to lose a great take--it's not so good to use for reinventing someone's voice.

So don't worry so much about the graph! It ain't no disaster.
