Question about Shearwater default GF low settings

[tursiops]

increased risk from yo-yo diving is probably not covered

There is a whole consensus conference and report that suggest this does not appear to be an issue.
See also https://www.researchgate.net/public..._yo-yo_diving_profile_on_air_for_fish-farming where one conclusion is that you need to watch your ascent rates.

neither are multiple repetitive NDL dives

RDP Repost covers this; repetition is not an issue so long as one takes residual N2 into account.

Thank you for these links.
The slides about yo-yo diving profiles add faster compartments to the model but don't show experimental data, so they can't show if the modified model has an actual impact on real-life DCS risk of yo-yo diving.
RDP is interesting in that they really tested it with repetitive dives, and measured more Doppler bubbles after the 3rd and 4th dive of the day (p.51, C.1). Assuming more bubbles correlate with a higher DCS risk it would indeed indicate that the model underestimates DCS risk in repetitive dives.

Unfortunately, that's not what correlate means. Your conclusion requires a casual relation (not a correlative one).

There was a plot of bubble scores vs. clinical DCS from somebody's study (Doolette's?) in a thread in Dr. Decompression not too long ago. I am failing to find it now, of course, but it is rather enlightening as to the "correlation".

Especially the one DCS outlier with fairly low bubble score.
