When using the Left Edge (Figure 3-76), the grade tape follows
the cut/fill status of the left side of the screed, regardless if
elevation reference point is at the middle or right edge of the
screed. The cut/fill number in the elevation control key is tied
directly to the Elevation Reference point.
The Elevation Control Key reflects the elevation reference point.
