Different speed results from BT

According to The BT broadband speed test at
http://www.productsandservices.bt.co...ON-TOTAL-BB-R1
my connection speed should be 256k (I am 3.5 k from the exchange).

But I've just used http://speedtester.bt.com/ and got the following result:

Download speed achieved during the test was - 1122 Kbps
For your connection, the acceptable range of speeds is 400-2000 Kbps.
Additional Information:
Your DSL Connection Rate :1632 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 1250 Kbps

Why the difference?
