Yun, Sorry for the slow reply. I am not sure one or the other is preferable, but it would seem to be better for the term to share the implicit variable with the equation that nominally solves that variable. I have never tested this issue so I don't really know or have any good mathematical reasoning, just a hunch. -- Daniel Wheeler
