Is the BT Speed Tester on something?

[#1]

I did a BT test today and got

Quote

Download speedachieved during the test was - 6023 Kbps For your connection, the acceptable range of speedsis 1000-7150 Kbps. Additional Information: Your DSL Connection Rate :7869 Kbps(DOWN-STREAM), 444 Kbps(UP-STREAM) IP Profile for your line is - 4936 Kbps

The IP Profile does seem somewhat odd, as for the connection rate it is both incorrect and non-existent in their profile list.
I wonder what could be going on. Thoughts?

It's best not to question it too much for your own sanity.
The BT speedtester chucks a wobbly every now and again, we're keeping an eye out though for any widespread issues.

Too late a warning, Mand, there are plenty of other things that have implanted my insanity
To save opening a thread, I have noticed a mismatch of your profile and BT's: PN 6500; BT 6000; Synch 7869. Isn't the BT one wrong?
