Wazz how old are you? Your posts are driving me crazy!!!
I had a repull last week as my power levels were -6dBmV and that is the best the engineer could get them as they were originally -12dBmV where i was getting huge amounts of packet lose which you can see from the graph below, the cable was replaced for a far thicker 1 and a 3dB FPA added to the back of my modem and my power levels are now 0.5dBmV and with an ok looking graph i think.
Just make sure they check your levels before leaving!

p.s i was charged £49 for a repull.................. kidding it was FREE of course.
