Wayne, thanks for taking the time to do that. If only the careful work of this kind wasn't totally swamped by the loudly held opinions of the very large number who have no idea of what "controlled variables" are.
On your note below, I have to say good luck. Mainly because for many manufacturers it involves speaking through a pleasant but technically ignorant person whose English is just comprehensible to an Engineer who speaks only Chinese. Both communication paths are fraught! I speak from experience. Not a criticism of them of course, just a fact of life for those of us who are inadequately monolingual.

If only we could get to the engineers at Hyperion et al, we might get some sense!
