There is plenty of elevator to counter MCAS, but has the pilot enough strength to pull the control column to do so, even when speed increases to 380 kts, given that the artificial feel increases with speed ?

It seems the only chance not to crash, if manual trimming was not possible due to elevator up forces, would have been reducing power, airbrakes out, to cut the speed, then flaps down to kill MCAS and use electric trim again...
