This whole conversation is a BRILLIANT illustration of the very issue that caused the OP to start this thread.
We have what appears to be an intelligent woman, judging from her writing. She made a decision to do something that has caused an almost unprecedented thing -- unanimity on ScubaBoard! Despite a great many people with a lot more experience and training, and approaches ranging from harsh to very gentle, telling her that what she is doing is unacceptably high risk, she remains adamant that it is not, and that she will continue to do it. Furthermore, she has dismissed the entire body of collective wisdom about the kind of dives she is doing as being overly conservative.
You cannot change those people. They are not stupid and may not even be ignorant. They are arrogant in a particularly dangerous way, because they just aren't swayed by the input from anybody except someone who is telling them it's okay to do what they want to do. These personalities exist in every sport and probably in every walk of life. The only thing that EVER changes such people is having a close brush with disaster and surviving it . . . and as I know well from the ER, all too often, such people are capable of an internal dialogue that convinces them that the accident they avoided or survived was not due to their error in judgment, but due to some other factor which simply wouldn't apply if they were to persist in their behavior.
