I get 33 when I look at Beersmith. For a partial boil, that might be right for calculation, but it seems good when I've tried it. I've read that you can't taste a difference between 5 IBUs, so maybe that's way it tastes ok with this amount of hops.
As far as mash temps, I like to mash this one high, to give the malty taste and higher FG.
