The more enclosed and lengthened you make it, the more benefit you'll see. If you can make it go around the sides and bottom, do it. If you can make it extend two feet back from the hatch, do it. It's very much what you put in is what you'll get out.
Other mods like wheel covers and skirts and belly pans will compound the benefit.
