Dan,
What he posted was, "I made sure the reticle was focused and checked for any apparent parallax issues, but did not see any." He did not state whether he did this at both 100 and 200 yards. A lot of shooters assume that once the reticle's in focus, there is no parallax.
He has also never stated the magnification, objective lens diameter, etc. of either scope. All of which would have some bearing in the question, even if the reticle's in focus. Have seen considerable parallax with a 5-15x German scope at 200 yards when set on 15x and the reticle's in focus.
