Peter, three weeks after the previous post I am very disappointed that there has been a total of only 7 replies, of which I have contributed 3 or 4. I am disappointed because you obviously have important things to say. Please do some consulting about the best way to communicate your ideas clearly. All your good work seems to have gone down like a lead balloon. As I said before, and sincerely constructively, your points were difficult to comprehend, and I am still not absolutely convinced that I have understood clearly.
