It's not common knowledge, just saying. Some of these are a little off though. Brewer's Gold is 38% myrcene and is reminscent of black currents, which is atypical for an American IPA.
For a comparison:
Magnum: 1.8 total oil / 32% myrcene
Millenium: 2.0 total oil / 35% myrcene
Galaxy: 2.5 total oil / 37% myrcene
Chinook: 2.3 total oil / 37% myrcene
Apollo: 2.0 total oil / 40% myrcene
Summit: 2.0 total oil / 40% myrcene
CTZ: 2.5 total oil / 45% myrcene
Warrior: 1.5 total oil / 45% myrcene
Nugget: 2.0 total oil / 52% myrcene
Ahtanum: 1.0 total oil / 52% myrcene
Cascade: 1.1. total oil / 52% myrcene
Centennial: 2.0 total oil / 54% myrcene
Super Galena: 1.8 total oil / 54% myrcene
Northern Brewer: 1.8 total oil / 55% myrcene
Galena: 1.1 total oil / 58% myrcene
Horizon: 1.8 total oil / 60% myrcene
Simcoe: 2.3 total oil / 63% myrcene
Citra: 2.5 total oil / 63% myrcene
Amarillo: 1.7 total oil / 69% myrcene
I found that the 35-45% myrcene hops are more dank, piney, and pungent, whereas the higher amounts are more perfumey, citrusy, and tropical.
