Wow, I had no idea I had been bent that much...

Lamont, don't worry, I'm sure we can find some tables that show you that you weren't bent.....;-)

whether you are in the n camp or the he camp is a matter of personal choice, how "you" feel. imho if you are looking for black and white science to define the variables about different subjects physiology, you won't get it. My choice for shallow helium 150fsw or less was driven by wanting sobriety, it had nothing to do with ndls or time spent in the water on the hang. I got sober, I feel good post dive, I dove the plan and did the time. I will leave the disscussion of deeper than 150fsw to the divers who spend time there.

helium is just the bees knees you guys. all the cool kids are doing it.

Any video or pictures from these perfect dives? Screen shots of profiles? We're listening... I'm sure liteheaded and others would love to hear more about mixed gas topics you have no formal training in and no experience with either (again) - yet for some curious reason demand scientific "proof" of the validity of everyone else's experiences.

I think that our conversation with Richard is not so much oriented to deep air vs helium, but more about ratio deco and how it is validated. I have not demanded much scientific proof about much in this thread. But in a recent thread I did demand the scientific proof. The intent of my demanding scientific proof is not to debunk it. It is an effort for an accurate characterization of the methodology. I do not believe that it is accurate to say that the three pillars of ratio deco are dissolved gases, bubble mechanics, and deep stops. IMHO there has not been any research work directed at studying ratio deco and dissolved gases or ratio deco and bubble mechanics. I'm still not sure why deep stops has a "pillar" status. And as I said before, the fact that there is no research work does not negate the fact that for some people it works very well.

I am no dive god and no scientist eminence. But at least I know enough to identify when someone is trying to sell me fecal matter calling it pomade. I am the first one to acknowledge when I am wrong or when I do not know an answer. I am not above asking you (litehedded), AJ, James and even Richard for enlightenment in a subject matter that I think you guys may know more about than I do. I've done it in the past and I am grateful for the things that I've learned from you guys. But there are certain things that I just have to call them for how I really see them.

You're not going to get scientific proof of ratio deco. I've yet to talk to anyone who seems to be on the exact same page with it.

 

[LiteHedded]

I don't have much to add with regards to how ratio deco is validated. ratio deco isn't how I conduct my dives. I'll let the west coast guys handle that stuff. I would imagine it's along the lines of 'we aren't getting bent'

kind of the same way I validate what I'm doing.

I would imagine it's along the lines of 'we aren't getting bent...

...too much'

 

[LiteHedded]

...too much'

again, very similar to what we're doing

Yup. I have used it for over 800 dives, including dives down to 270.

Despite the small variations between people (partly due to tweaks over the years, partly due to different interpretations) it's never been an issue to agree on a schedule.

I have had two issues during this time, one on a dive to 270 when I was scootering with a video camera. Our team was last to surface and the trip leader asked us to scooter the CCR guys "deco station" over to the boat (a contraption with 8 pounds of lead, crossbars and floats)

Once on the boat I had a pain in right forearm which did not respond to O2 but went away with ibuprofen.

Similar issue recently on a 120 dive (after a 190 dive) where our boat anchor was slipping so we blew off 5-8 mins of O2 deco. Again, right forearm and did not respond to O2

I think thats a pretty decent enough record for me to accept.

YMMV

Pain in the forearm. That's not even worth missing practice over
