Examples of the trouble with using stats and opinion to prove the safety of any item:

1. An operator states that one of its recently acquired electronic systems is presenting a near 100% serviceability rate and proposes to hold it's new maintenance regime as the model for other systems to aspire to - until the revelation that most crews don't use it, or even switch it on, and the only reason it's so trouble free is that no-one is actually using it. In fact, the few times it is used - it doesn't work! Overnight, the system becomes the worst performing in the fleet.

2. After 25 years of "fault-free" flights an operator of fifteen jets congratulates itself with a big party - just before which, it finds that it has 14 component overruns - over their Life Limits - and has to ground the fleet for two weeks, almost losing its AOC/M/145 approvals.

Complacency and confidence is what makes most accidents happen.

ATG,
You display that generic aircrew confidence in an ability to judge what is right - without, I rudely assume, either qualification or experience in this particular field.
