How do you know it is targeted at 9db?
Where does that info come from?

When BT had upped it my ISP: Plusnet _told me_ it had been increased from 9 
top 12 dB,  I requested that it be changed back to 9dB since the only effect 
that had been achieved was the lowering of my synch rate (and hence IP 
profile and measured d/l speeds) by around 800 kbps.  No increase in 
connection stability had been gained.  So BT reduced it back to 9dB.  If you 
monitor your SNR margin it will hover around the target.  Mine varies 
between 8 and 11 dB but mostl;y around 9.5 dB.
