Just how accurate is BT adsl availability checker

Friend wanted broadband but wanted it with BT.
I checked BT wholesale site availability checker and it said because of the length of the line she would get probably 256 speed and an engineer visit might be required.
I told her to order anyway to see if she would get it .
She rang me yesterday to say she had received router and that service was live but she didn't know how to install it.
I popped round this morning and set it up for her.
Guess what the sync speed is..................

just over 4mb.
So just how accurate is the BT database ?

Re: Just how accurate is BT adsl availability checker

its estimated (so could be close, could be wildly inaccurate)
im not sure they know what route each phoneline takes from the exchange. (pretty key into giving a good speed estimate)
However, now theres been a BB service running on it, anyone who goes to use the line in future should get a more accurate speed (im pretty sure they update it when someone gets BB on the line, and it supports a stable rate)
but i could be wrongSmiley

Which could be a clue as to why it was wrong - perhaps a neighbour has dodgy wiring and had only reported very flaky service.
