Well if that is true than I might owe peterj an apology.
I just still refuse to believe that my beers are coming out to as much as half the bitterness as I'm shooting for. I'd like to think I'm enough of a seasoned hophead to notice if my partial-boil IPAs and pales were coming out under-bittered, especially to that degree. In fact, I can think of a couple where I over-did it, but if you're correct, then that should have been impossible without a full-boil instead of a half.
