"Riding your Computer Up" vs. "Lite Deco"

[boulderjohn]

In line with this "methodology"...
Ascending from a scuba dive, | deep stops, |ascent rates, |safety stops, | time limits, | and gas needed

There are statements in this document that are very questionable in light of current research. Just as one example, the pure faith in the importance of deep stops is very much in question today.

Exactly what I was thinking. And....what decompression algorithm is Departure's Decompression Software based on?

Good point but in light of the "Deep Stops" in Chart 2 being 2 minutes or less - it may or may not be helpful in a Recreational manner. My Oceanic Veo 2.0 has the option to include or exclude the "Deep Stop" when diving deeper than 80 feet. Again it is only a pause for a minute or two.
This is not exactly a Decompression Strategy but I agree with your caution.

I'm glad that BRD went there.

I understand that any ascent profile can just add in a deep stop(s) purely for the sake of doing deep stops. I've done them when it was cool to do so. Never noticed any difference. There are still a few proponents of this profile even today.

Please consider the following question carefully, it has nothing at all to do with the effectiveness of deep stops. It is about when the remaining proponents of deep stops would first institute them based on depth.

I now believe that even the proponents of deep stops don't see the need/benefit for any deep stop at recreational depths and times. Is this correct?

I personally noticed a big difference when i started doing deep stops when doing 4-6 dives per day in depths of 90 to 130 feet with most dives going close to, or slightly into the deco range (on Nitrox). It resulted in a dramatic reduction in "pole spear elbow" which was pain in my elbows after using a pole spear a lot. A 90 second or 2 minute stop at 50 feet seemed to be the cure.

I do not think deep stops for recreational profiles are valuable. I tried this concept and also and found no difference in my post dive feelings. Of course, I also do not think nitrox improved my post dive status when I dived to the same nitogen exposor Deep stops for deco dives is hotly debated but is confused by definitions.

For most recreational divers calling it a deep stop is kind of silly. Its more like a deep safety stop and I think the jury may still be out on this one. If I don't send my DSMB up at the bottom I will usually pause in this range to shoot it. Not an intentional "deep stop" but probably works out that way.

I think of "lite deco" as very limited deco obligation possibly monitored and adjusted in real time within the recreational range that may be done by experienced dives with either formal or informal decompression theory and practice based on dive conditions, back gas and ideally with redundancy.

For me it is a way to approach dives with a very conservative dive computer that hopefully gives me safer dives with reasonable bottom times.
