In BSAC training you do AAS stuff more than once.I disagree. Using "training" as what is practiced is not redefining words to suit, it's what training is. Practice is what develops skills and I have a very difficult time believing that bsac (or anyone else) would seriously expect ingrained skills from a class once, rather than consistent skills that are practiced with every dive and built through experience.
Are you honestly claiming that the kind of people who dive an Air2 without an octopus are practicing using it for OOA ascents frequently?
Practice and training are not the same.
TRAINING | meaning in the Cambridge English Dictionary
Training
the process of learning the skills you need to do a particular job or activity:
We got two weeks of on-the-job training on how to conduct interviews.
competition, you exercise in a way that prepares you for it.
PRACTICE | meaning in the Cambridge English Dictionary
the act of doing something regularly or repeatedly to improve your skill at doing it:
So when BSAC say that people revert to training, they mean training not practice. You are saying that the practice replaces the trained response. They are explicitly saying that is not the case and people revert to training. In the BSAC case that is because in a couple of hundred OOA incidents over 10 years there was a small number of primary donates and one primary take. Mostly people did as originally trained, which in BSAC’s case is secondary take.
Training is important, practice is important too but without training and learning practice is not useful. Practicing the wrong thing is not good.
