I didn't account for the Coriolis effect, oh my.
As well as the influence of stars, planets and asteroids, and certainly you forget account the expansion of the universe
I think you understand what I am talking about. We can only say that we have an LDE (or something), witch response to some influence (change setpoint, disturbance) differs from the response of the plant to some SSE (or something). And this is correct for some range of the plant states.
