I agree with you here.  It's not simply code superiority that matters but a 
balance of attitude and the code's corroboration with numbers.  Both had 
numbers to show but I think that one's attitude was preferred over the other.

I don't see where credit was lacking.  As far as I've observed, SD's author 
was given acknowledgment on what he did and even got praise.

Thank you very much.
