should there be any need to worry about his downstream being about in line, but his upstream being high? seems like there is something about the plant that i would be looking at. granted, there is a frequency dependence on the behavior in the line, but if i see both levels out of spec, i think problem with the general line. if i see one good and one borderline, i think that there is a bad fitting or splitter or something.
maybe i'm just paranoid or imagining things...
