That's well above an average beer gravity. As I said, I do partial mashes, so I usually use about 3 lbs in a go. Even so, a beer with 10 or 11 lbs would exceed gravity of the heaviest beer I've ever made (and that used mostly LME because I wanted Munich).
So if anything, I think this thread has demonstrated that you have to run your own comparisons, because the results depend on your assumptions.
