If they worked in that situation, they aren't wrong. On the other hand, if they just barely didn't make things worse, they might be wrong...in that situation. That shouldn't be a matter of style, but a matter of objective analysis of the situation. Given that most techniques look like crap in real use, it would be difficult to term anything "wrong" unless it's nearly always going to make things more dangerous (like telling a yelling person to "calm down").Okay. My experience is that it always comes back to one of these four explanations, which is well documented in several years of reading these threads. I look forward to your non-self serving analysis, where you don't start discussing all of the things you teach that would actually have helped her survive better, or the things that she did wrong that still worked, but you teach your students never to do.
