Ibus are a shit shoot is what I've been finding out lately also depends on what scale you use Tinsenth -Rager ( mo
Actually listening to a podcast yesterday from brulab where this guy has shown large cold side dry hop amounts can actually absorb iso alpha acids (introduced on the hot side )and actually reduce bitterness.
Also percieved bitterness and measured bitterness are two sepperate things iso humulone (also i herd oxidised alpha acids )in dry hops imparting also a .66% increase in bitterness giving reference to purported bitterness from large dry hop amounts being a real measured thing!
Dont quote me on this havd a listen to find out for yourself i think its pretty Cool.
That's where I always rekon let your pallet decide for you and adjust hop amounts next brew to compensate
