Good point.Keep in mind that we don't know for sure that this problem and "the big circuit" are related. My guess is that this is a separate problem but that the result of this one is used in "the big circuit". But we don't really know that for sure. It's best if we try to keep a thread focused on the problem of that thread -- if for no other reason than someone reading this thread has no idea what is meant by "the big circuit".
Thank you.
