I expect, like myself, people are curious as to how the supposed last-ditch backup that is the manual trim wheel actually works in extreme load scenarios, how it interacts with the motor, and whether it's fit for purpose. That is entirely relevant to any discussion of MCAS, runaway trim, etc.
I'm not sure why you're in such a bad mood over this, but none of your links contain the answer to the question I and others have about the design (unless I've missed it) and saying "do your research" is not particularly helpful. We're tying to understand. With the depth and breadth of expertise from various contributors on these boards, it's surely not too much to make the query, and hope that someone who has the answer will reply.
