Well there are generally two disconnects. One is with reality vs. what people online say about how they do things (ie. people tend to exaggerate if not lie, which I don't think is happening here, btw) and two, the difference between reality and people's assumptions.
There seems to be a lot of assuming that if it's possible to conform to standards and run a bad class that this is what people will *want* to do. I don't think people usually intentionally do this. Many instructors are self-conscious beings who try to improve their performance over time. Sure there are truly bad instructors out there who do cut corners and "rip off" their customers by giving them lousy training, but usually these instructors aren't following even minimum standards. Usually they don't care about standards.
The same can be true if someone goes too far in focusing on quality to the point of putting their students through an ordeal to get certified. This used to be the norm (I've heard) and there are still some instructors who do this. I have to honestly say I would feel more comfortable with an instructor with an obsession for quality than one for an aversion to it, but I'm not sure that obsessive focus on quality to the exclusion of price and/or students needs and wishes is necessarily the best model of instruction we have.
Maybe there's a middle road. In fact, I'm sure there is. You'll find lots of instructors on Scubaboard who are looking for the middle ground and some of them are probably finding it at least some of the time.
In any event, there is a difference between "methods" and "results". On boths sides of the issue people defend their own methods and over the whole I don't see a lot of people getting in line to listen intently to the methods of people who don't teach like they do.... I'm guilty of this too but I try to keep an open mind. On the subject of results, I think Pete might be right. I think you can get good results in different ways and that some of those ways are more "efficient" and/or more "effective" than others. Putting your students through an ordeal to get certified isn't the only way to get good results.
