No human being could SCUBA anything even approaching the mariana trench.

In SCUBA anything below 100ft is considered deep diving.

@ZVCorrupted

Isnt that basically what I just said? I feel like im missing something here.

@kerosene

@kerosene That just sounds like smoking weed with extra steps...

@Jojothegoodperson Oh no, very sorry to hear that. Why?

@Pat

I missed the reply from you originally. Nice.

@Chrisleon27 @lefarfadet

@Chrisleon27

Short for "decompression". It is where a deep sea diver is unable to ascend to the surface at a normal pace and must stop at certain depths and sit there for extended periods of time (up to hours) to off gas (get pressurized gas out of their body) before being able to ascend further.

It is the type of diving I usually do and is called "deco diving" or "tec diving" (short for technical)

@lefarfadet @Pat

@Pat

Ahh ok, well thats fair then.

Yea my caution of course reduces the risk, but the risk is still quite high compared to normal activities. You can dive completely within the rules and still get deco sickness and die. So while i may make the risk more manageable I think its safe to say my tolerance is still higher than most.

COVID-19 probably raised the IQ of the gene pool by a point or two for sure :)

I think there is a big difference between not having brains and simple risk tolerance. You can know all the risks and have a high risk tolerance. You can also be an idiot and do risky things out of ignorance yet have a low risk tolerance.

I would say I have a healthy but relatively high risk tolerance. Afterall I am a deep sea cave diver (among other things) and cave diving is too risky for most deep sea divers, let alone non-divers. I'd say that alone puts me pretty high on the risk-tolerance spectrum.

That said I have an extreme attention to safety measures well beyond your average diver I'd say. So a big part of my own risk tolerance is confidence in my abilities.

@lefarfadet

@Pat

To give you an idea at the depths I dive (400ft/120m or so) I can do about 15 minutes bottom time and expect about 2 hours deco, so its manageable... but sitting in one spot in the water for 2 hours can be very boring for many people. Either way at those depths and time it is doable.

@lefarfadet

@Pat

Either limited by how long they stay awake or their risk tolerance. For the guy who died he cut the time too short and his risk tolerance too high. He died and many of us suspected he might. The team that was responsible for him ont he attempt that killed him is actually the same guys that did the earlier portion of my dive training. They arent a bad bunch of people but their risk tolerance was too high and I never quite liked their safety approach when I dove with them which always felt a bit rushed.

@lefarfadet

@robryk You can always ask @cwebber she (name change since publication but same person) was the main inventor of activitypub. They are usually very friendly and might be willing to point you to your answer or a resource better than I.

@robryk You can always just look at the raw API results for a post and see what it looks like. I dont have an answer for you off hand sorry, was a while since I touched that code.

@Pat

yea, though as i stated in my other reply the guys who do commercial diving are at saturation, so its not entierly comparable. A world record attempt is just a touch and go.

@lefarfadet

@Pat

I'm not a saturation diver, even when i go 120 meters I'm down there a short period to ensure I dont approach saturation.

Attached is an example of a decompression schedule that would be used if you saturated at about 180 meters in the ocean, so a bit farther down than I would ever and have ever went. The time at the top is in days:hours so your looking at 7 days of decompression in a tiny tube for just a few hours or work.

Should give you an idea why an open-circuit record attempt where you decompress over the course of hours instead of days is kinda a death sentence.
