They want to be helpful, but you just can't do a serious analysis like this over the internet.
To be fair, I don't think LaLeLu came here with this story looking for answers. She seemed quite certain that what she believed to be the circumstances that caused the prop & strut failure were the only possible explanation. But to some of us, that explanation just didn't hold water (no pun intended.) I don't believe anybody accused her of neglecting proper maintenance and if anything, I think our goal here was to simply alert her to the possibility that her assumptions about the incident might not be correct. In that respect I think this discussion has been valuable (although I suspect LaLeLu does not see it that way.)
But you are right, the real answers will lie with qualified technicians who will do hands-on inspections and tests.
