What do you do, as an instructor, if you have a new student arrive with a rank in your style, but from a class/club/association that has, for whatever reason, gone it's own way long enough ago that there are significant technical differences - for example, stances are different, patterns are done differently, preliminary/preparatory motions are different, trajectories are different, etc? Do you accept the student's rank, but require them to change the technical details to match your own organization? Do you make them start over, but let them move faster? Does it matter what rank they are when they arrive at your class?
As a student, how much are you willing to modify what you've learned in the past in the above situation? If the instructor said you had to relearn techniques you'd practiced for years, what would you do? What if the instructor required you to start at a lower rank? What if you wanted to start at a lower rank so you could make the technical changes, and the instructor didn't want you to?
