Before marking the pavement, the person holding the rod will do what last step during crater profile measurement?

The last action is moving one more step toward the stanchion to bring the rod into the proper reference position for an accurate read. This placement helps ensure the rod is at the correct distance and aligned with the sight line so the crater profile is read with minimal parallax and error. Stepping to either side or away would put the rod off the intended reference plane, leading to an inaccurate marking.
