Yes, everything pretty well maxes out quickly. 150 minutes bottom time is the beginning of the max zone. Intermediate stops become counter productive beyond a certain point, and you just get cold and take a ppo2 beating. I move up and use the gradient to the max. I like that strategy especially well in light of the fact that we have such a huge oxygen exposure at that point that if we toxed, I would want to be well past a lot of the deco and not have incurred a bunch of loading at those depths so as to have a better chance of living through an emergency surfacing. I feel a lot better when I have decompresesed to within 40 or 50 feet of the surface. Time there seems like home free to me. Hanging out there does nothing in my opinion - no window, no real change in ceiling per time , moving the gradient is the best aggressive move. Personally, and I am not recommending this to anyone else, I basicly blow off the 40 foot stop almost completely , as in do 20 out of 120 minutes and move up to the 30 foot oxygen in the habitat, or jump the 40 , do a skimpy 30 and do the oxygen at 20 for inwater dives. If I get wacked there, I just drop back down and try again in theroy, but in reality , when I do get wacked doing that , I stick it out and it goes away in minutes, like 3 or 4 minutes. I generally hold real still if I suspect it and then I am fine. Again, I am not suggesting anyone else should do that , but by the same token, if you have no preconditions and are in shape, deco is no big deal. Intermediate stops need to be done with an eye to the window effectiveness and the gradient. If you do longer steps at the higher ppo2's and shorten the lower ppo2's but move rapidly through the gradient, you end up with a more effective deco overall , it is faster, and the sooner you get closer to the finish line, the better you can handle a big problem , and the lower the risk of the dive at the end of the day, and that is what it is about . Identification of the risk is tough for many of us because we got taught such slathering stupidity out of the training agencies, but of course, now there is an alternative.
