Bill, you're a smart guy, and very helpful, and you share much valuable information, but - that's really overkill.  And by the way, the confusion here is really EF's fault - "Smooth Shading" is how it's referred to in the P7 manual, and the term "Phong shading" is never used in conjunction with what you're describing, only with the lighting node of the same name.  The manual really lends one to believe they're the same mechanic, they're actually covered in the same section (chapter 15).  You're operating under different assumptions and definitions from those set by the manual, and while yours might very well be more correct, it doesn't help anyone for you to get irritated when someone leans toward the manual.

There's no reason for a ginormous slam-dunk large-font post justifying your sharpness up front, you could have just let it go by and that would have been that.  If you recognize you get along with almost nobody, and that people find you bombastic, as you say, then you might do well to curb that instinct.
