Yes, Scott, the numbers are outrageously excessive, but the real reason for making the little deep stops is to be sure to move out the gas without seeing bubbles deep that will be impossible to remove later as they grow due to pressure drop. Once up higher ( way up ) bubbling is not so bad a way to get rid of gas, assuming no preconditions, shunts or large vessels in the capillary beds, but combine what I am saying to get your answer. On the other hand if you have made a high ppo2 gas switch deeper, then you can see how greatly this does in fact reduce the need for long shallow stops over an above the benefits discussed above. Scott - relearn all of ths stuff for your own account and throw the old thinking away. It is dead ass wrong, and we have proven it. Everything we do is now being explained by some other methods, meaning that the old stuff is garbage, and the fact is there are things we have yet to openly discuss that will also make these supposed explanations baloney as well. Let's keep the dialogue giong on this stuff and step through it cafefully. I do not want you guys discarding what I am saying and just thinking I am some freak. My whole team does this , and they can not all be freaks. Besides, I am the oldest guy , so there goes that theory. Also, my natural paranoia and years of taking badmouthing from the Brett Gilliams and Tom Mount's and having everyone else in the dive industry try to say I am an idiot tends to make me suspicious that you think that way as well, and are merely hoping to expose me as a moron in this duscussion in a polite manner. Let me tell you this - if I am an idiot, the Naval Warfare is a bigger one, because they believe me, and as everyone knows, I lead from the front and do not opon my mouth about everything that I have not already successfuly done.
