As I said, I'm just making suggestions based on observations. If you were to remove the clef and any signatures (like those band parts that aggressively save X-space), then there would be an optional barline or bracket at the start of the staff, followed by r16 after a tasteful space. So, as far as NullVoice is concerned, those decorations don't exist, and it looks as if even the tasteful space before the r16 disappears as well. Cheers, David.
