Just wondering how accurate the estimated speed quoted (52 / 17) and how long it takes for the speed to stabilise. I had my ADSL converted Wednesday am seeing 40 / 6 speeds . I have run several speed tests and the ip profile for my line is 41 / 20. Was a little concerned as when the engineer (non BT) installed it he couldn't get a line test or a sync test as he hadnt been given a EIN number so couldn't contact BT
