I am trying to figure out how do we know that Rogue brewery, specifically the brewmaster, uses the Ranger IBU formula? Also I couldn't pick up John mentioning the AA% of the whirlpool hops.
The whirlpool hops shouldn't result in significant IBU so the AA% isn't significant.
Per information available on the internet, Dead Guy is 40 IBU. The CYBI recipe is 49 IBU (Rager), but about 5 IBU's of that calculated bitterness is because they entered the whirlpool hops as 1 min instead of 0 min.
I brewed this and made a note to adjust the bittering addition to make 40 IBU Tinseth in an attempt to get closer to the commerical bitterness and leave the whirlpool addition (10 minute steep after flameout for me) the same.
Overall, the beer was excellent and is on my list to rebrew this year. My other changes for next time include:
1. Using a 10L Munich instead of the Weyermann Light Munich (6L) I chose the first time.
2. Mash at 154F for less attenuation. I'd use Wyeast 1056 again, fermented at 63F.
3. Shorten the boil to 60 min, adjust bittering addition for 40 IBU Tinseth.
