The value of a training course is often dependent upon the Instructor that teaches it.
My instructor was one of the top IANTD instructors of the day having been trained directly by Tom Mount, sat on the IANTD Board and is in the Woman's Scuba Hall of Fame. It was the program that was lacking, not the instructor.
Hal is an experienced Deep Air diver, who I would have thought would run an excellent program. If you wish to discount the value of this type of training because of your experience, that's your prerogative.
You dodged my question and are avoiding my point. Sit and spin, sit and spin.
