I'd also note that the assumption that there is "little to fear from the inexperienced" tends to assume a duel situation. Using myself as an example - I generally don't have issues dealing with one extremely inexperienced fencer. However, outside of duels there is nothing stopping that one fencer from bringing a few friends. Two against one is a problem. Three against one is a much bigger problem. Past that point, any victory of the one becomes some miraculous thing to be celebrated for years.
