It's not just a matter of strength to operate the trim wheel, which can vary a lot depending on the mistrim forces. It's also fatigue from pulling back on the yoke. And it's also altitude. That means time is a factor that has to be taken into account. There are configurations where a mistrim flat out cannot happen at a certain altitude or it isn't recoverable in time before hitting the ground, regardless of strength.
