Now look: The Butterfly Effect is a very limited theory that had no place in FA Cup draws. When Lorenz developed it in connection with his efforts at weather prediction it was an interesting intellectual exercise to try to explain the sensitivity of his model to small changes in its initial parameters instead of trying to find out why his model was so touchy in the first place. It, and Chaos Theory, have their place in certain fields but balls in a bag is not one of them. I am certainly not dismissing the theory nor the views of any other poster.
