In my experience (not professional nor expert, just made a lot of beer) that chart seems pretty accurate IF you had instant chilling at the end of the boil. I think that the time delay between shutting off power and getting the wort chilled is why the near flameout and flameout hops are used. A flameout addition that steeps for 10 mins until the wort gets down below 140 F is kind of like a 10 min addition on that chart. I struggled with this with my old setup, where I'd gravity drain through a CFC. I could get great flavor, all the bitterness I was expecting, but for a while I couldn't get decent aroma from kettle hops. I ended up having to double the final addition, and throw it in the kettle when about 1/2 of the wort was drained. YMMV, but this worked for me. with the slower chilling system.
