Fred, you can't take raw theory and expect it to apply to the real world, we have so many more variables entirely because of scale that can effect it as well. The scale alone brings along it's own set of principals that only apply to this, once you move onto giant scale, it's another, more traditional scene and you can whip out your textbooks and spew off what ever is said. There is still largly much being innovated and explored in the venue, just please, don't be turning your plane into a lawn dart because you are thinking full scale theory alone.
