I am inputting a recipe from the July/August 2006 issue of Zymurgy (Stone 8th Anniversary Ale) into Beersmith as a reminder to brew it someday.
According to the recipe in the magazine, the IBUs should be 55.  When I put the listed amounts into Beersmith, my calculated IBUs are 40.  What gives?
The obvious: Yes I have the right hop form (pellet); Yes I have the right times; Yes I have the right AA %
