Correct me if I am wrong but you can't actually dual wield with great weapons, so no need to put them in the dual wield charts.
Another thing to take into account, and it makes things even I think, is the fact your probability to hit with two attacks is lower than with one. So it still makes the 2H weapon do more damage on average in most situations.
Flanking does screw things up as it's way too powerful and exploitable right now.
