Overshooting NDL and mandatory deco stops

Hmm

Why fact-check a good story?

12l tank with 200 bar start. 150 bar after 25 minutes at 25m.

Cool story, bro.

I have been on dives with many PADI instructors who ignore NDL.

What is the back story here? Were they gas-limited rather than NDL limited? Did they get DCS? Did they have a computer? If so, did they violate THEIR computer or what yours said? Need more info to understand your denigrating statement.

Dude, your SAC is impressive :-D

Yeah. Actually seems unlikely, unless/even if he is very small and a smoker (I don't understand the physiology) but they seem to have lower SACs).

My guess is his numbers are wrong....perhaps the pressure gauge is way off, the time is wrong, the depth wasn't right, whatever. I'm putting this inthe highly skeptical pile unless some more evidence is shown.

We dove with a PADI instructor yesterday. First dive max 63 ft, around 53 minutes. Second dive max 47 ft. At 45 minutes my Oceanic showed NDL of 51 minutes. His Suunto had him in deco. He had dove the day before. I think you could blow off a lot of deco with the Suunto at times.

Perhaps unlikely, but not impossible

Here is a dive from my last trip to Bonaire, warm water, good viz, no current. One of my better dives, comes in at 7.61 L/min. Though I do pretty well at gas consumption, I would imagine there are quite a few who do better.

And I was happy that mine had improved from 25 to 14 lol

Thanks. Being a large chap at 6 foot 1 and weighing near 290 pounds ( weight is dropping lol )
I often hear people chatting about how my air won't last long on dives.

Good diving techniques and not chasing the marine life with help.

My guess is you have not dived with me and you are allowed to be skeptical. My numbers are not wrong, there is nothing wrong with my air gauge, my own personal equipment not rental gear. I'm sure you think the Shearwater Perdix gave me the wrong information on the dive as well as the air gauge being incorrect.
