I've always understood the values to represent the distance to the center of the craft. Not actual weight distribution. I don't think the value should change if the battery was mounted 12 inches below the frame or 3 inches to the right of center. The value needs to be changes in relation to the distance the IMU is from center of the aircraft. I don't believe we are concerned with weight distribution here.... Please correct me if I'm wrong.
