This correspondence has continued for over four years, and it is probably appropriate now to close it.

John Knowles has submitted a reply to the last post from Doug Landau, disagreeing†with much of it. Anyone interested in his reply can ask him to see it by emailing†jayknowles34@gmail.com. He accepts the decision to end this post, believing MP is not the† best place for the technical treatment of the subject.†
