You want backlash, eh? Well, this statement of yours is just a bunch of nitrox propaganda BS which is taught only by the worse, most clueless agencies. The goal, knucklehead, is to keep your PP02 as low as possible during the working portion of your dive and then use a higher PP02 nitrox or 02 for accelerated deco. Keeping your PPO2 at the high end for the entire dive will fry your lungs and risk a tox. What agency and instrokter trained you? This I would like to know. Safety results from proper dive planning a "clear head" BEFORE you get in the water. The gases are simply what is needed for the dive and contribute nothing to the safety. If your EAD is deeper than 130', then clearly your dive plan is not safe. If your PP02 exceeds 1.02 in the working portion then your dive is not safe. Exposing nitrox as some sort of magical substance which can perform miracles like you state is a bunch of dangerous bullshit and it seems to me, my friend, that you need to go back to the drawing board before you kill somebody.
