WatchoutBelow,
In some respects you are right, but just because an individual passes a test on a given day does not make them competent.
I try and instill a survival instinct in my students.
I know a lot of people in the industry, and the only thing that matters is to me is that they fly well, and come back alive. We all make mistakes (that's how we learn) but I know that some commercial guys could not cope with say a stuck lever at near max power, and some private guys could.
There is no industry way to allow for this, but ability is ability nevertheless.
I am ALWAYS happy to learn from the examiner(s) who do my check rides , coz one day they may keep me alive.
Fly safe
