Calculator: https://www.brewersfriend.com/ibu-calculator/

Good evening all,

So I created a recipe for a strawberry NEIPA that my friends and I will brew during Thanksgiving. The problem that I am having is figuring out the utilization percentage for my hops and the IBUs. The in-recipe calculator is saying I should have an IBU around 40 where as the independent calculator is giving me a value over 160. Could someone help me with these issues? I am also confused to what is an allowable utilization percentage for boiling, whirlpool, and DH. It seems every place I look gives different answers. Thanks for your help in advance!
