What I really enjoy is the fact that you laid it out all so nicely. Not my intent to pull a code review on you but I have to say something when I see some quality code especially when it proves such a valuable point. The code is nicely formatted (even though the forum slammed all your stuff to the left), well documented, and follows most best practices like using 2 part names for objects and using a consistent format. Adding to that, you actually tested for something more than a small handful of rows, included the results in your post, and added a complete additional explanation... this is some awsome stuff. I'd recommend that you actually DO turn it into an article for SSC especially since it trashes one side of a myth and proves the other.
