It sounds like these all assume every pleat (for to-the-sett) will look identical on box-pleat. Is it possible to break up certain patterns over 2 or more pleats, like knife-pleating does, or is that why a large internal overlap of the hidden portion is required? I wish this thread had come up 2 or 3 weeks ago before I started my first box pleated kilt! These formulas are great!
