Very good info... Yes, I was puzzled by the partial boil since I have been doing full boils. I also used the extract hop schedule with my full boil. That said, my IBU's must have actually been roughly as high as what BeerSmith calculated.
I guess it's a good thing that I'm adding hops to my AG version if I want it to be closer to the extract batch I made. From what you're telling me, I think I do need to add even more hops than what I have planed from this discussion...
