See Paper Path Status test for a description of the configuration encoding. Reports the highest peak during the first quarter of the lifting interval. Reports the interval between the initial power min (when the plate is not yet engaged), and the point where the lifting power becomes a constant. Reports the average power over the center ¾ of the lifting interval.
