This is just so true. I don't have the only take on how long or short dive training should be. I know what's right for my students and me, and I share that.Peter no Instructor has to satisfy me with how they teach their program. The important things are to satisfy the Client, the Agency and more importantly their conscience. If this can be done, that's all that's necessary.
But the topic of this thread is about exceeding a person's training. My point, is that they have often learned that it's OK to exceed and violate their training right from OW. If mixed signals are sent, don't be surprised when the result is chaos. The human mind is amazingly facile at justifying poor decisions and actions. You can question what is sufficient training till the cows go home, but if your training includes bad habits that have to subsequently be broken or techniques that are contra-indicated then you will produce mixed results and a producing a decent competent diver will take a lot longer. It's my opinion that contradictory training, which is the predominant style as far as I have seen, creates an atmosphere where exceeding your training limits not only makes sense but makes the offending diver feel that they are indeed emulating their instructor. Why are we surprised that this happens so frequently that its almost a given?
And Peter... you don't want to set the bar high or low: set it neutral! That's the one skill I see lacking for many, many divers. They are led to believe that it's something you work for and that only experienced divers can attain. Shenanigans! That's the first and primary skill my students master. If they achieve nothing else, they will have great trim and buoyancy. That by itself will keep them from getting into a lot of the troubles I see divers get into.
