Hi Neal/Aude,
It would have been simpler -- and more to the point -- to just say, "Bill, I cannot answer those questions because I do not know."
That anyone can respect. But, you always insist upon loud pontification and blustering; your trademark.
So, okay, I am taking this as an "I don't know" answer.
Nice chatting with you, Neal.
God bless, have a wonderful, blessed day,
Bill
