I asked Dr. Weinstein about this directly (on Twitter) and his response is (I think I am being fair here) that this isn’t developed (he says “instantiated”) to the point where you can predict things, or even reproduce known behavior. At this point he is guided by not much more than mathematical beauty, he doesn’t expect that it is a correct theory of physics yet.
