A brilliant post, I just passed this onto a university student who was doing a little analysis on this. And he in fact bought me dinner because I discovered it for him.. :)..

If possible, as you gain expertise, would you mind updating your blog with more information? It is highly helpful for me. Two thumb up for this blogpost!
