Exactly! A single TAC figure doesn't give you any idea of what percentage you and I get on our Adsense accounts. It's my guess that Goog had to stick their necks out a bit to promise the big boys some guaranteed revenues (youtube). Some of them may even be getting 150% of what Google actually made on ads served to their sites.
