I just had this fron VM tech

" Ideally, for the
downstream modulation that your modem is running on (QAM256) we would like
to see the levels between +6 to -3dBmV but these levels are a guide and we
can see devices working fine outside these levels."

Ok well how come 3 VM tech guys say that it should be 3+\- ?
and when I post on the newsgroup that my levels was 4.0+ they said "We will have to send a Guy round to fix it" ?
talk about moving the gaol posts.
