Well, it's good to see all those concrete facts that we can check out if we have any questions. Otherwise we would think you were making everything up.
Speaking of that, let's look at this: "No one should attempt to use a drysuit during a course without having at least 20 shallow shore dives using a drysuit." Is that your opinion, or are you saying ti is a standard? If you are saying it is a standard, well, I'm having trouble finding it and will need you to help me. I wonder how that works in the OW certification course, since students are allowed to use drysuits during their certification guides, provided that they have had a confined water introduction first.
You also said, "There are many tech/rec instructors who don't have what it takes. I know of one particular case where an Advanced Trimix Instructor failed a diver, who then bought his c-card from a mutual friend." So how does a failed student purchasing a card from a friend (how???) prove the instructor who failed him does not have what it takes?
