All true.  And all discussed before, as Chris pointed out earlier.
Earnie and others are being very helpful to the OP by reviewing this
stuff again.

It's great to ask questions and explore boundaries but what's better
is to explore new boundaries and ask new questions.  I'd also encourage

been said on this subject so far so that any further discussions will be
engaging for all.
