Ahh. I got sidetracked I guess and was wondering how far (mm, inches, yards, kilometers) past infinity "past infinity" was.

Like you said earlier... I've never seen nor heard of a Nikkor that didn't stop at the infinity index mark. Something wrong with that lens probably. If the infinity index is offset, I wonder if the others are equally offset.
