I read the book Real-Time Rendering, 2nd Edition. Somewhere in there it say:

The experiment is base on http://www.rastertek.com/dx11tut10.html. Am I missing something? I didn't find an errata for the book on its corrections Website, and my first-languages isn't English, so maybe my vocabulary understanding is wrong?
Does the Shininess means the Brightness? Or what else?
