I have no idea what speed the line is synced at, all I know is that all 
my downloads happen at a shade over 800 kilobytes a second, according to 
firefox. If they we're a lot slower I may have logged into my router and 
checked the minutiae but so far I've had no need to look that particular 
gift horse in the mouth. Indeed I had expected to get a high 7 what with 
the overhead so I was surprised when I got a generous 8 out of them. 
Maybe the line is "synced"  at a higher speed then throttled elsewhere? 
If you are very curious let me know and I'll find out for you :)

Roger.
