I was reading one of his books a long time ago. I got to a point where it talked about using calibration (raising the arm). I thought it said that you can't get an accurate answer if you are inquiring about something that has an emotional connection to you. At that point I stopped, because all of the questions that I would want to inquire about have some emotional tie to me.
I didn't not buy the course, I was reading one of the books. Do some more research. This is just my 2 cents.
