Is that just slopping practice or commonly accepted practice?
My thought on this fwiw is that in places like ORD, where you have a often times VERY busy approach controler, most of the planes are in a narrow range of altitude and speed, so its furthur unliely that 13k could be confused for 30k.. as it would really stick out.
