Yes, this is old news, your friend Roy already brought that link up way earlier from his Google searches, and it has been discussed and refuted already.

That's amusing. Half wit blogger you say -- attack the source but not the data or the methodology. Somebody who outlines his data, shows the math, and comes up with his own results.  Its called "research" and its definitely not for everybody -- some folks want to skip right to the end and be told what to think instead.
