With the cube hop addition calculated as a 0 min addition I get 34.3 Ibus (as per recipe). With the cube hop addition calculated as a 20min addition I get 55.6 Ibus. Then you guys are saying the 5min addition would be like a 10-15min addition totalling over 60ibus. Thats almost double the original IBU's. And I can say this beer is nowhere near 60+ Ibu's. Swill drinkers are loving it. And I have also had Mark try it. I believe its bang on the 34 Ibus. Anyway each to their own. Debate over.
