If you want to provide evidence of widespread problems requiring massive change, you need to provide evidence of a need for massive change. The fact that a handful of people with individual experiences are unhappy does not constitute any such evidence whatsoever.
Well over a million people get certifications each year (all levels). The last statistics I saw from PADI alone had them certifying over 900,000 people a year. There are bound to be problems with that much going on. Consider how much time and 3expse we spend on training doctors and giving them licenses to practice medicine. Yet there are about
20,000 malpractice lawsuits filed each year.
If you want to convince the entire WRSTC that it needs to make massive changes, you will need to show more than a rogue instructor here or a training death there. If that's all you've got, then the scuba industry would take it as a sign it is doing really well.
So what statistics can you cite worldwide to show a systemic problem?
