The issue that the simulator trim wheel forces are lower than in the actual aircraft - so it is not a simulation, and we/most do not know at what stage the manual trim wheel will not be able to be moved ( near full forward or not far past natural, in seconds of a runaway trim). Given the manual trim wheel is hardly used in normal flight, most pilots I expect would be very surprised in the force required to move a moderate out of trim stabiliser. That comment based on known history and recent reductions in trim wheel size - they certainly did not make "it" easier to move!

This was a recent discovery, so your training may not be relevant in a real case of survival incident - but you would pass with flying colours in the simulator.
