Update
I have accumulated what must approximatively be 50-60 penetrations so far.The penetrations in the 80-86 range seems even less frequent than the warhead malfunctions so far.
If you want a more scientifical experiment, with maybe 50-100 (not 1000 of course)tests and the results for each written down, I am willing to do that, although it will take a few days.
