The Bogaerts thing was merely an example of how people misunderstand advanced metrics. I opened with a statement about one of the problems with advanced metrics is that people don't understand them. And then I said "FOR EXAMPLE" to actually notify people I was making an example. Seriously. I should not have had to explain that.
And this "I didn't say that comprehensive is a bad thing. I just believe that "comprehensive" can be used as a metaphor for "unduly complicated"." You exact words. Copied. Pasted. Underlined.
Seriously? If you are implying "Comprehensive" is a metaphor (when I think you mean "synonym) for "unduly complicated, but somehow you are simultaneously saying that doesn't mean it's a bad thing!?!!? In the same sentence?!?!!?
When you use your lines about things having too many parts being more likely to break down, those "too many moving parts" are exactly the factors that make it more comprehensive. In fact, now you have been touting "KISS" as the logic in determining a defensive metric. Well, keeping it simple does make it far less comprehensive by definition of the word. And please do not tell me that you have a simple method that is more comprehensive, as the words "simple" and "comprehensive" are actually antonyms.
