I have just started using BeerSmith. For my extract brews I like to boil all five gallons that I will be using (actually I start with 5.75-6 gallons to account for boil off). I entered my MegaPot 8 gallon into BS with the info below. When I switch the extract recipes from the standard 2 or 3 gallon boils to my kettle the IBU's go through the roof. I have to cut the hops in half or more to get the IBU's back near where they started. Does the hop utilization really increase that much by doing a full boil? Did I enter something wrong? Any help would be great.
Thanks,
Kevin
