3) your statement "I cannot decide, what kind of action would induce the lowest risk - following an RA, not following an RA or flying without TCAS at all as the basis for my risk evaluation would be episodes. I think the same goes for you as your information basis is still only episodes." is irresponsible.
You have shown over and over and over again, that you draw conclusions without any statistical information. This may well work for you, but in the real world claim have to be supported by evidence.
I am not willing to make any risk assessment without the appropriate data to found the results. If this is irresponsible for you - I can do nothing about it. But I hope that I will never rely on
your risk evaluation.
