I've already posted this to the BrewSmith Forum, but figured that someone here might be able to explain what's going on faster.
The IBUs listed on the grid (33.3 + 10.1 + 9.2 + 3.9 + 2.5 + 5.4 + 6.0 + 5.5 = 75.9) don't sum up to the IBUs listed under bitterness (105.4) for my recipe. Any idea what is going on? I do have a late Extract addition.
