In mathematical terms, ">" means "greater than", and ">>" sometimes means "much greater than". Anything beyond that is merely exaggeration on the part of the writer, and speculation on the part of the reader. I suspect, however, that it would be like saying "much much much greater than" -- rather childish, although sometimes we do that on purpose for humorous effect, such as "evah" or "!!!1!". You got a problem with that? This is a message board -- if you're going to post publicly, expect responses from anyone. If it was meant to be a private communique with jpak, then PM him.
I should go "take the piss". BRB, GGPP.
