You have been DIR brain washed

First of all, I'm not DIR brainwashed - if you've read any of my other posts you would have immediately noticed that. BTW, I'm the one who coined the term Holistic Hogarthian in order not to be confused with DIR mentality. I think for myself and try out the things which could improve my diving - decompression being one of them, and I can guarantee you that a lot of my knowledge comes from personally trying what works and what doesn't.

\"First off you can run your dive on v-planner with 100% then plug in 80% it's the same run time........\"

There is a huge difference between what a deco progarm tells you and what your body tells you. I used EAN80 in the past until I made the switch to O2, the difference was tremendous: no more post-dive fatigue, and ready to go right away. Run times don't mean anything for the O2 portion of the dive anyway: if you haven't been doing proper deep stops, have been using too high a bottom PPN2 or PPO2, too fast an ascent, etc., you can use whatever gas you want in the 20ft range and still will not decompress properly.

\"Second the 100% o2 induces vasoconstristion and that counters the real off gassing\"

As FMT already mentioned, if you have to stay a long time on O2, you take backgas breaks. For every 10 minutes on O2 I go 2 minutes to my backgas. TDI, I believe, tells you to switch
after 20 or 25 minutes and not to count those minutes toward deco. Guess why I get out of the water 15 minutes sooner than then ones using their EAN80 and not doing backgas breaks. BTW, the backgas breaks reset the lungs so you can use O2 for extended periods of time. Otherwise, explain how there's cave divers doing dives with a total bottom time of 300 minutes at 300ft, doing more than an hour on O2 and still being able to go for a run after a 14hour dive? So what is the real offgassing?


\"Third check out pages 61-65in your TDI trimix diver manual\"

It's the typical BS of the ignoramus - every little kid can play at home with a PC program and come up with some results to show their superiority. Did TDI publish the Doppler studies, whcih compare subclinical or silent bubbling when using O2 compared to EAN80. No! Again, diving is a reallife sport, not one that's done behind a computer or from a manual.
