As a Marketeer in a previous life, surely he realises EVEN if it's real, if people think it's too over the top, they think they have to be bogus letters.
Part of the problem is what he does now, he's done the ebook, done the vids and the mindnumbing 500 odd seminars he's done.
I think he's promoting the stuff through other mediums, and looking for new outlets for his business flare.
Also, and this has always been my beef, if he was a Munchkin he would have so much more credibility with his material. He's not exactly 5'2" bald and 180 of pure lard, now that would be impressive.
