Walter,
"I believe it is important to understand the concepts of partial pressure to understand decompression concepts and oxygen toxicity".
Ok, lets agree to disagree then...I don´t think pp is important in understanding decompression concepts (and I do not believe oxygen toxicity should be taught in OW). As for not calculating pp02 while teaching about it, it was entirely my assumtion that teaching about pp02 also included calculating it (propably because calculating helped my understanding of it). The more we discuss this the part of instruction about pp02 in your class seems to be shrinking...maybe this is because I associate pp02 with Nitrox classes were pp02 is a big part and because you seemed to "make a big deal" about including it in your teaching or maybe I misunderstood you...either way I feel that the gap between our views seems to be shrinking, do you?
I am not going to argue about whether what I said differ from what I meant to say or not (as a more unproductive argument is hard to find).
Truva,
I don´t understand the point of the first part of your post..."If you are safe diving to 30 feet then your next problems with depth are keeping track of how long you can stay and dealing with nitrogen narcosis."
I couldn´t agree more...
"I am suspect of any program that does not recognize how it is being used and adjust of it. If it doesnt then it is only in it for the money and it doesnt have its students best interests in mind."
To my mind, criticizing any system, from the point of view of those who don´t play by it´s rules is like saying that laws are bad because people brake them...Maybe speedlimits should be raised because people are obviously driving too fast...somehow this argument doesen´t stick and neither does the one (if that is your intention) about divers violating the depth rules of their certification.
Maybe you´d care to elaborate?
