I agree that diving experience means nothing. I could have been diving for 50 years and be a horrible diver. Of course I could have been certified and only make 1 or 2 trips for diving every 3-5 years. Then there is the person that has 4-5 years diving experience with 800-1000 dives. To a diver time means nothing for experience. It is a combination of the number/quality of your dives.
