==As I suspected, you are completely disengenuous.
Well, given that it was PSS who challenged the O.P. and subsequent links, and then refused to answer them, other than to say “take my word for it”...let’s just say he appears to be a tad less than candid.
Hey, I pointed out three specific criticisms of the article, and no one countered those criticisms. If you wish to discount that, so be it.
And if you wish to argue over how a GA operates, then it is incumbent upon YOU to learn how they work first. I see no evidence that you really understand how they operate (much like the author of that article).
So if you don’t understand how they work, and don’t want to learn how they work, why should I try to force you to understand? Wasted effort...
