For an "official" coastdown you would be required to work with your back-to-back paired runs with each direction reflected,which theoretically would cancel any grade effects of the test road.
But as Metro mentions,you can definitely see a 'trend' if doing back-to-back runs,same piece of road,all same direction,with and without mods,as close together as you can on same day.
