I am sorry that I have said that. Let me take back what I said above.
I was upset when I considered you and others blocking the more optimal
solution and in favor of the less optimal solution. That is my short
temper, as usual.

Now I can see that you might not see one as more optimal than the
other as convincing as I do, or I haven't done a good job explaining
it.

Let me offer my sincere apology. I will reply to the technical aspect
of the question in other email.

Chris
