A driver could plow into a bus stop full of little old ladies, an airplane pilot could crash a planeful of kittens into a kennel full of puppies, and a boat captain could sail into a vitally important bridge. You can argue that checking them is necessary to protect the others. As a thought...

No. How do you diagnose a heart attack or a stroke that may happen on a dive but may not happen on a drive back from the clinic?

Workman's M-values are already greater at depth, and the argument behind deep stops was that they're "too much" greater, esp. for the fast tissues. Gradient actors were invented to "flatten" them. You should look at Workman's work to see how exactly he arrived at these slopes.

Well it's not that far left off the pier... yes, technically it's a different "site", but just like the Buddy reef, you can dive it from Sand Dollar.

30-32 pounds is a common wing size for cold water single tank diving. Depending on how you do your rounding, it'll come to about 16 litres.

It is pretty much the same house reef. Buddy's side is arguably better, more of a wall, but there is stuff in the sand to the left of SD too. And the little boat. I have a feeling Buddy's packages work better for 6+ people, SD is cheaper if you can all fit in one unit. They will bring you an...

I'd say attack helicopters, but those were just hovering in place. There was too much silt for a good shot of the entire formation, this is the best I managed :( PS. you can catch them in the daytime.

It is: you jump in the water, swim around, swim back up. Just like you do at light'o'clock.

I'm not sure DSAT M-values given in e.g. Powell are what the DSAT computers are using: they may be the ones used for creating PADI tables but tables come with built-in safety margin: you seldom spend all your planned bottom time at planned max depth. Buhlmann's numbers were apparently adjusted...

No, I meant what you said: the slope is parallel to the ambient pressure line. It's `Pamb + M0`.

My understanding is they just use M0 all the way down as the model was not designed for decompression diving in the first place.

M-values are not calculated on the fly, they don't change with repetitive dives. The actual M-values are different but similar enough: check Erik Baker's Understanding M-Values. Yes, they do affect the NDL/deco schedule on each given dive, but the accumulation over repetitive dives is...

Follow the numbers. DSAT tissue compartment half-times are 5.0, 10.0, 20.0, 30.0, 40.0, 60.0, 80.0, 100.0, 120.0, 160.0, 200.0, 240.0, 360.0, and 480.0 minutes. ZH-L16 TCs are 4.0 or 5.0 (pick one), 8.0, 12.5, 18.5, 27.0, 38.3, 54.3, 77.0, 109.0, 146.0, 187.0, 239.0, 305.0, 390.0, 498.0, and...

Moreover, that is one of Bruce Wienke's "gradient reduction" factors built into RGBM. There's plenty of us vacation divers using RGBM computers diving next DSAT and lately: ZH-L16 computer users. Empirically, they don't seem to get bent any more than we do. That strongly suggests that purely...

The bottom dweller. And happy there, too.

That would work in this case: DCS hit on the last dive of the trip would add to the "last day" peak, QED. ;)

True but if "DCS stress accumulated" during multi-dive multi-day trips, you'd have a bathtub distribution with peaks on both ends of the trip. I mean, we know it does if you keep doing 6 dives/day to the no-stop limit on air, and yet somehow lots of LOBs are not returning to port full of bent...

If true, that would suggest the exact opposite of DCS risk increasing with repetitive dives.

:rofl3: I have a strong feeling that Buhlmann's a and b coefficients are given to 4 decimal digits because they were printed to %5.4f format mask. Welcome to Scientific Computing for Life Sciences.
