You're not alone in your confusion. It's difficult to determine where the goodies are because most of the "so called" explanations are couched in technical terms which make them less likely to be assailed by the rest of the board. If one explains something in highly technical terms, an opinion magically morphs into a fact and less likely to be challenged. This fancy footwork often ascribes heroic qualities to the "expert". :>) It also doesn't hurt to ignore a request for a clear explantion(in lay terms). :>):>)
