If I dont adjust my hop additions, my beers end up WAY too hoppy... much hoppier than thier IC'd counterparts.
Not going to argue the fact here, but this was explained back in early '09 in BYO along with a temp. chart to show the reason that late hop additions in no chill wort were contributing so much bitterness to the beers. I based my brews and chart on this information from the Aussies that they took thier cues from in the publication.
If no adjustment works for you, keep doing it, disregard the chart. I do what works for me, you should continue to do the same.
As for aroma... I always prefer to dry hop for aroma.
