I personally am not buying it , that people understand it as much as they think they do , or to the point *that it can be applied , accurately to add much value* with so many factors simultaneously exerting influence . This sincerely isn’t meant as a dig to anyone.. I believe people want to believe they understand things more than they do so they can forecast longer out and it’s sort of cutting edge stuff to do that . I just am skeptical based in that , I think the more moving parts there are , whose weights can ebb and flow that it results in to many potential outcomes to be used and then correctly identified and weighted . But thus is just me trying to explain my skepticism .
