Oops! Guess I should have scanned down through previous posts. Just saw the one from alcal with a similar issue. That does bring up the issue of IBUs contributed by steeping. I can see where steeping from flameout (i.e. boiling) could contribute bitterness but cooling to 170F before adding hops for a hop stand really shouldn't. My understanding is that this is about aroma, not bitterness. I don't know if there could be a way to account for this in the software. Seems unlikely. It's not a big deal to just disregard the bitterness addition in the future. It's just wierd how the calculation changed overnight.
