I wouldn't be surprised if you brewed the same recipe with half the hops it would taste very similar and the difference in bitterness would be insignificant if it was even perceptible.
Another factor you didn't mention was water. A 100 IBU beer with a high sulfate content in the brewing water may taste more bitter than a 300 IBU beer with a low sulfate water. Since you mentioned it wasn't extremely bitter I wonder if your water was low on Sulfates. Try adding a pinch of gypsum to a glass of the beer and seeing if it increases the bitterness.
I don't doubt that for a minute. I have a pliny clone that is supposed to be 172 ibu and a Dog fish head 90' ipa that is supposed to be 111 ibu. The DFH feels so much more hop saturated than the Pliny. I was in a pissing contest with a homebrewer of mine. Plus had way too much hops.
I was just having fun and making sure some good hops whouln't go to waster.
I don't know about my water and can't be bothered to find out. When the beer is good it is very good..
As a homebrewer I couldn't care less about the wate.
