As for the others, who turn "Master" into an actual prefix, like an academic or aristocratic title, why on earth would they do such a thing? How much it rubs against the grain to call another person "master" - I can't even stand these ceremonies where people grovel on their knees to become in-door students. Your actual level is your level, nothing else.
