Somewhere in the tutorials or on the beersmith website it talks about setting up your equiment and it says you should set your hop utilization to 100% and that there is very little variation at homebrewing levels. It says that bigger batch breweries actually start going up higher, to 200% and 300% levels. Check the beersmith guide on the website about setting up your equipment to see that discussion.
