I'd say if you hit a charger with enough damage to knock him back but he stays on his feet and keeps coming, you didn't knock him back: that was just an abstraction in game terms. What really happened was your hit slowed him a bit but he kept coming. That's easy enough to abstract.

As for a stop hitt always stopping a charger, I don't agree with that. You could hit with a glancing blow that slips off to the side as he moves forward or something like that. Especially if you're using a non-impaling weapon. With an impaling, thrusting weapon, the mechanics are clear that your opponents is impaling himself on your point in order to close the different, and if he's not strong enough or strong-willed enough, he will stop.
