These are all obviously good methods of deciding whether the ball is in or out of bounds but on the edge? How much leeway do you allow for movement of your fishing line/dental floss etc? 1 millimetre? 1 micrometre? On the edge is an impossible decision as no measurement is exact, just as accurate as the measuring device you are using allows. Have you really seriously announced that the ball is exactly on the line rather than just inside or outside?
