So the maneuver starts with a rolling section and ends with a “point” section. So, roll, point, roll, point, roll, point. Then reverse roll, point, roll, point, roll, point. So the center is at the conclusion of the 3rd point where the reverse roll segment begins.

>>> I still disagree. This maneuver has been flown since the late 70’s, early 80’s. The center has always been considered to be the point where the roll reverses. Don’t forget the last wing level is a “point” and should be considered a part of the maneuver.
