Well if those stats are correct you have a very good line indeed. You either have a very good quality line or live very close to your exchange.
It sounds like it could be a data base error in the BT line checker.
Just to clarify please enter phone number
HERE and paste the results back here (minus your phone number at the top).
At the end of the day it should not really matter so long as you get ADSL max, as it will sync with the exchange as fast as your line will allow regardless of what any checkers say.
