The original rationale behind Deep Stops, was to mitigate the chance of a Fast Tissue type II Neuro DCS hit especially with high Helium bottom mixes. Although recent studies are now challenging this idea (i.e. the high diffusivity of Helium coming out of solution early in the ascent, forming free phase bubbles in the Fast Tissues), you should take this into account when deciding to omit Deep Stops: are you willing to risk a rare but possible type II DCS hit for the sake of not late supersaturating/loading your Slow Tissues (per the Conclusion of the NEDU Study)???
The best most prudent compromise to practically apply from the NEDU Study & discussion for those using Deep Stops is to extend out the O2 profile at 6m such that you have a surfacing Gradient Factor of 60% or less (per the readout of a Petrel Computer upon surfacing from your O2 deco stop, or alternatively setting the GF99 function to 60 during the O2 deco stop) --to ensure inert gas elimination from those Slow Tissues. This is especially warranted if you're doing multiple deco dives per day for a week or more -and I would also recommend taking a day-off/break after three consecutive days of multiple deco dives per day to further off gas residual N2 from Slow Tissues, as well as reset CNS/O2 exposure.
I absolutely reject this NEDU study for any indicator of deep stops or the effect in decompression.
Why? The emphasis in the title is mine:
Redistribution of decompression stop time from shallow to deep stops increases incidence of decompression sickness in air decompression dives
The divers went to 170 FSW on AIR. They had continuing increase of N2 Loading because they were on EAN21.
Given that technical divers choose gasses for the best mix for the dive they are doing and their decompression plans, the NEDU study does not apply.
