petitfromage,
You are probably right in that the OTP shouldn't be viewed as a real indicator of performance. The crews know this. The management verbally and explicitly mentioned this. But the probelm is: did the management honor their golden words? Unfortunately, can we know what might have actually happend there, esp between the management and crews who couldn't made the 20 mins by just 2 mins. If you (as a crew) got some words from your supervisor, can't you say those 2 extra mins is no more important than your bug's life?
