Thanks for this Bob U - very helpful - I will read your paper with great interest - it was nice to learn that not only am I observant but also obversant or perhaps you are the obversant one - all kidding aside I believe your insight is extremely useful and I am passing it on to Deacon's group Terry and the Pirates. - Bob L
