The management of a dynamic scenario does not always require a complete understanding of the primary cause of the situation. If you can diagnose it and completely deal with it then fine but most are hybrid and complex. The Skip is interested in risk alleviation and he/she did a good job imho here. That is of course perceived risk alleviation in an intensely time limited environment.
We often learn collectively from post incident inquiries but need to use our judgement in 'live' situations.
There is little more frustrating than a 9 month inquest eventually finding that we were slightly too/insufficently risk averse at the time when we only had a very short time to assess and deal with a problem.
