Kingpatzer:Given the explicit contentions presented that PADI standards require a diver to be granted a certificate when they are a lethal danger to themselves and others and present a statistically significant risk to themselves and others due to the "minimum standards" it follows as a logical conclusion that all PADI instructors who follow PADI standards are complicit in the creation of inadequate divers, as well as in the act of endangering others' lives. The conclusion which immediately follow that is precisely a comment about the morality of PADI instructors as a whole.
PADI standards are written in such a way as to make them difficult to understand as well as easy to miss various points. It is fairly common to see experienced PADI instructors disagree as to what is and what is not required.
It is fairly difficult for folks who are not PADI DMs, AIs, or instructors to get a copy of PADI standards.
Many students aren't very aware of the concept of agencies.
With that in mind, it's probably rare that a student has any idea what is required for certification. They only know what their instructor tells them. Most students, even those with poor instructors, think their instructor sits at the right hand of God. Instructors run their classes, adding in what they feel is important. If it's ever questioned, they can quite honestly say they did not require the additional skills, they merely asked their students to do it, they students did them and there were no issues.
