First off notice that your keyboard actually has punctuation and a shift key. I really don't have the time to read your giberish 5 times over to try and understand what you are trying to say. You are giving me a headache!
Ok. It wouldn't matter whether they measured from the center conductor or the shield because most splitters have a zero DC resistance from center conductor to shield anyway. So, what's on the center conductor will be on the shield and vice versa. Is it possible that someone used a sat or DBS "power passing" splitter instead of the normal CATV 1000Mhz type? That would be the only explanation for a difference between the shield and center conductor because these splitters do not have a zero DC resistance between center and shield so they can pass power to a LNB or multiswitch.
Sounds to me like the cable service drop is not bonded or not bonded properly to the service ground. Also possible that they are using a VOM that has a high impedance input and would give a false reading unless loaded.
