T, if you're really interested, spend some more time on their web site. Without giving away all the details of exactly how the method is done (then they wouldn't have anything to sell, right?), they have a lot of detailed info about both the method and it's performance. One thing that they don't emphasize a lot but it's in the fine print: They have a money back guarantee on the course fee. It's a pretty liberal guarantee in that you could take the entire course (which would obviously give you a complete understanding of exactly how the method works) and then if you don't like it or change your mind for whatever reason they will give you 100% of your money back no hassle. I think I saw somewhere that about 1% of their students take them up on that guarantee. Anyway, it's one of those things where you really don't have anything to lose other than the time you would spend going through the course. Once you complete the course, it's totally up to you whether you implement it in your account(s) or not.

And just to be clear, I'm not trying to sell you or anyone on this. Just take more than a cursory look at their web site if you're really interested. There's a lot of stuff on there. Hope that helps.
