The problem with your logic is that it denies the reality that there are differences between, say, a 360 and a double cork 1080. One is simple, one is radically different and more difficult.
If somebody asked "how do I climb up tuckermans ravine" it is not the same if somebody was like "how do I climb nanga parbat alpine style" even though they are both climbing related.
Asking how do to a dub cork is a bad idea. I would wager (if this guy aint a troll or a dumbass) that he, or pretty much anybody that asks, doesn't have many of the fundamentals or predecessors down to make it a reality, such as various corks, reg spins, flippy things, all sorts of shit. If you are solid at a large variety of tough shit, you can figure out how to do a dub cork, ESPECIALLY with so many quality vids out there that one can "study" and learn from. Somebody already mentioned that you don't see pros (or pro-ams) asking how to dub corks. They learn by trying, but also they have a solid foundation and a deep bag of tricks to draw upon, whereas so many jiblets these days try hard shit so quickly with some severe consequences.
