Not bad - Is bad - Not bad
Rubicon research repository on reverse diving profiles:
(and as is typical for any research, one has to read it very carefully, as the devil is in the details)
2000: "We find no reason for the diving communities to prohibit reverse dive profiles for no-decompression dives less than 40 msw (130 fsw) and depth differentials less than 12 msw (40 fsw)."
Proceedings of Reverse Dive Profiles Workshop.
2005: "There is now sufficient evidence to demonstrate that FDPs and RDPs with analogous exposures within the recommendation of the Workshop have different decompression obligations, with the RDPs being more hazardous, at least in some situations. We conclude that the current practice of advocating forward dive profiles should be retained at this time."
Reverse dive profiles: the making of a myth.
2006: "Edmonds, McInnes, and Bennett fail to impose the desired level of uncertainty on the subject of RDPs, in the context of the Workshop's findings and conclusion, and have added little to the debate that took place at the Workshop. We find no reason for the diving communities to prohibit reverse dive profiles within the no-decompression limits for dives less than 40 msw (130 fsw) and depth differentials less than 12 msw (40 fsw)."
