JamesK, maybe I am reading too much in your reply. I agree, this is not data but just a presentation with conclusions, no statistics to back it up.
James, I thought you had learned in school to distinguish between statistical populations and 5 individual cases. Just because some of these are recent, it does not mean they are a representative population of statistics that can lead to a conclusion, much more a rule for cave diving.
Here is some data:
1. Wayne's World, Nov. 2008: 2 victims, dive buddies - One had failed cavern 2x, the other was intro
2. Los Archos, Nov. 2007: 3 out of 12 students deceased - Not familiar with this one
3. The Crack, July 2007: team of 3, one deceased - Medical, Oxtox within established guidelines.
4. Peacock III, Jan. 2005: victim cavern certified, with 2 dive buddies - Intro diver beyond cert limits, doing 180 on air
5. Sac Actun, Dec. 2004: team of three, one deceased- Not familiar with this one
6. Ginnie, Aug. 2004: one victim, two dive buddies - I believe this one was the solo, intoxicated diver with no cave training.
7. Eagles Nest, June 2004: two people deceased - Terrible gas choices, and one buddy even commented that he wouldn't dive with the other one again after their sneak dive at Dipolar, for fear he could end up dead. However it was a buddy team, I'll give you this one.
8. Little River, 2003: team of two, one deceased - What was the victim's training level? I can't find it...
9. Devil's, 2002: team of 3, one deceased - Oxtox perhaps? Either way from the accident report it sounds as if the buddies got the victim alive out of the cave and CPR was attempted.
10. Little River, 2002: team of two, one deceased - Buddy pulled them out of the cave after a medical incident in a cave, giving them a fighting chance and was air lifted to shands.
11. Jackson Blue, 2001: team of two, one deceased - I don't know anything about this one, but from the report it sounds like gas issues which weren't solved by a buddy team, I'll give you this one.
12. Clarcsville Cave, 2001: team of three, one deceased - Unfamiliar with this death
13. Royal, 2001: two people deceased - Two OW divers, one within a week of class went into one of the nastiest caves around.
14. Cypress creek, 2001: team of two, one deceased - Unfamiliar with this death.
15. Emerald, 2001: group, one deceased - OW Divemaster diving deep air beyond training.
16. Sabak Ha, 2000: team of two, one deceased- Unfamiliar with this death.
17. Little River, 2000: team of two, one deceased - Intro divers scootering beyond where even full cave divers would scooter.
18. Forty Fathom, 1999: team of two, one deceased- deep air to 200ft. Well beyond any established training parameters.
19. Madison, 1999: two people deceased - Seem to be both trained, I'll give you this one
Plus a couple of recent ones not published yet:
20. death at Peacock in 2010, intro diver got disoriented, with a team that could not convince her she was not going to the exit, - Intro diver going beyond training limits
21. Jim Miller from WKPP. - I gave you this one in my original post.
I know I have missed a number of them, but this starts to build a real statistical population.
