So, you are not in any position to be able to assess the efficacy of the method, and your assessment is unjustified.
It sounds like you are frustrated at not being able to understand it, and personal grudge has led you to take a negative stance on it, as opposed to the only honest position you could take, which is to say "I don't know".
If you really want to know, but no amount of explanation is making sense to you, I'm sorry to say it again, but you'll have to go find out in person. It's really the last option for you.
