Agreed. The experiment actually gives an upper limit on the size of a molecule in one particular dimension. Still a very useful result.

  It isn’t necessarily an upper bound. The molecules might spread out more distant than their size.

    Wouldn't that provide an upper bound then? If the real size is equal to or less than the calculated size?

    In a very unlucky world, they can form a 2D net, with molecules instead of strings and a lot of tiny holes. If this seams impossible, remember that when water freeze into ice, it expands to a 3D "net" with empty holes.
