That being said, they also all agreed that no sim training for MCAS (or any of the other MAX differences) was a huge miss...
I suppose no one here will disagree with the above.
The unknown is and -remains -, when an how do you notice that the stab trim is doing something that you don't understand ?
In the real aiplane, with a continuous stickshaker, STS spinning the wheels and while running NNC's, how long does it take to notice the stab trim is acting up ?
One, two, ten, twenty seconds ?
The other unknown is, after the above number of seconds, is the out-of-trim recoverable with the manual wheels ? Or, at what speed and out-of-trim degree does the airplane become manually un-trimmable ?
Does someone really know, or do people just "believe", "suppose", "imagine" ?

Yeah, I know, "they shouldn't have..", "the trick is..".
But in the real world of real airplanes ?
