I've actually spoken with Paul Sutherland before, but we never really talked about the Fasttrack program in any detail.
Without looking too deeply, my impression is that they are basically providing a general financial planning and investment package, and charging management fees from the profits. That's simply my initial impression and it could be quite wrong.
However, I know they do provide a book about what they do, so I figure that if what they are doing is of any kind of interest, then to buy it - then dissect it.
I think the book's only something silly like a fiver, and if there's anything that doesn't add up right in the book, or looks dodgy, then at least you can see that without any real risk to yourself.
However, if you find it makes sense, then I guess the book's an investment.
Hope that helps.
