Hopefully one or more of our lawyers will weigh in on this, but I would imagine that distance would not be much of a factor. If you have a reasonable fear of death or serious injury, I can't see how that would lessen because of being at contact distance; in some circumstances in might even be reasonable to argue that the risk was enhanced by the closeness. (In the latter part of the sentence, I am thinking primarily of edged weapons, but choke holds, chemical weapons, and others could also be more dangerous with decreasing distances.)
