Stuart yeah thats correct, some people on adslgudie for instance posting and rightly so that they peed off with been 500m from exchange and haveing a line that 3km long, others post with say a 2km line and low attenuation but have massive noise on their line again slowing down their speeds. Its possible to have low noise but high fluctuation so bursts of noise that force BT to raise your SNR to make the line stable, again reducing your speed.

Likewise its possible to have a long line that has very low noise and it over performs but I think the former is more common then the latter.
