Do the shot pellets have to retain a spherical shape for the flow theory to hold up? For example, steel shot that may be less subject to shape distortion seems to flow through a shotgun choke in a different way than lead does. If the shot, or some of the shot, can be shown to become distorted, is their flight through air and disrupted air predictable enough to stay within the theory? Only asking, no other implications.
