I agree. I could never figure out how they get this to work. Seems impossible to determine exactly how much bitterness you will get with all of the variables inherent in the whole process.

Confirmation that utilization is independent of wort gravity:
BBR conducted actual measurements of the IBUs in 3 beers, one with a boil gravity of 1.127, one with late extract addition for a boil grav of 1.077, and one with a full boil at 1.068.
The same hopping schedule was used for all 3, and hop utilization is identical for all 3; the March 4, 2010 - BYO-BBR Experiment III:

(it also confirms that late addition can help make a lighter beer, though the effect is small).

I recently boiled some hops in water in the microwave in order to boost the ibu's of a batch, Seems to have worked.
Wish there was an easy way to measure the IBU's of home grown hops. I had to guess and I guessed to high.
