I agree, and maybe this is the reason why, in light of the current studies you outlined in your article, dive computer manufacturers haven't come out with Diver Alert notifications to stop using the deep stop function on their computers. In reality, what you are doing is simply creating a multilevel dive on a no stop dive. But what I wouldn't recommend is reducing your safety stop time because you made this deeper stop.If you begin an ascent within NDLs, and you decide to do a 2 minute stop half way up, you will still be within NDLs when you continue the ascent. Perhaps that is the reason people aren't falling all over themselves to do studies.
Maybe "deep stop" is actually the wrong term for these types of stops since they are not as deep as say a first stop from a 90 metre tech dive.They tend to be just one stop, maybe two but don't even follow the Pyle protocol so the sceptic in me thinks the added functionality was just a marketing gimmick to jump on the popularity of deep stops at the time. Due to the depth and time limits of recreational diving, they are more of an intermediate stop rather than a deep stop associated with a deep technical dive.
Then again, maybe there is something to it. No stop diving is different to deep diving in that divers can do up to 4 dives or more a day! They are accumulating and off gassing nitrogen through a series of dives rather than one very deep dive. Perhaps a different ascent protocol is necessary for this type of diving. While the slow compartments are very important during a deep dive, perhaps the fast and intermediate compartments take precedence during these shallow multilevel no stop dives. I honestly don't know but its an interesting issue. This is where more research is needed. And this seems to be still the case since @scubadada asked this question back in 2010.
