My understanding is MCAS change of stab movement was at a much faster rate than the manual electric rate. This may have been another factor that surprised the crews as it did not move like a trim motor would.
So twenty seconds of "back" trim may have been required before turning off the trim.
How MCAS mk 2 will move (as in motor speed) has not been released.
