How can I found out what total number of twoplustwo books were sold?

I played live 10/20 limit at the Borgata in Atlantic City on Saturday and the competition sucked. Maybe 3 out of ten players were decent. I could tell only one other read a 2+2 book from his style. So I figure that live poker in AC will be pretty good for a while.

On the internet, I observe there are much more educated players, especially 2+2ers, since the players are much more tight and aggressive, much more in line with correct/deceptive play. I find it difficult to run over these games, even at the lower 3/6 levels.

So I figure that maybe there a are hundreds of millions of fanatic players in the world, especially that televised poker has been pushed.

How many are educated by Sklansky's books? Your humble opinion on this please.
