That's certainly not my metric and I definitely don't believe it's a good one.
My metric is readability. The ability to return to a piece of code 6 months down the road and be able to understand precisely what's happening.

Oh, I know. It's very easy to add a comment that you think will help clarify things down the road, but instead, ends up being more cryptic than your code.
By definition, a comment is something short and half-thought out. It's a comment.
As I said in the post up above, stay away from comments. If you have to annotate, write documentation instead.
