who has tried Gerald O'Donell's Academy of RV/RI course

[Beero]

Hi I would like feedback on Gerald O'Donell's RV/RI courses, the ones that are available from probablefuture.com.
The reason is, I'm in the middle of the combined course, and as much as I enjoy following the tapes... I sometimes dowse to assess how worthwhile the course is and get very negative feedback from the pendulum.
If you have taken the courses, were you pleased with it, or did you think it was a waste of time?
Thanks in advance from
