Can Contention drop speed to 110.99 Kbps?

I am on PlusNet Broadband Plus up to 8Mb
Last night noticed speeds were incredibly slow, did speed check with www.thinkbroadband.com these are the results, which are similar to results from www.speedtest.bbmax.co.uk
31/01/07 17:25 169.84 Kbps 156.16 Kbps 87.113.208.147
31/01/07 17:33 275.21 Kbps 229.59 Kbps 87.113.208.147
31/01/07 17:50 340.33 Kbps 256.60 Kbps 87.113.208.147
31/01/07 17:59 462.60 Kbps 250.21 Kbps 87.113.208.147
31/01/07 18:28 279.46 Kbps 214.62 Kbps 87.113.208.147
31/01/07 19:58 139.20 Kbps 177.75 Kbps 87.113.208.147
31/01/07 20:27 110.99 Kbps 130.04 Kbps 87.113.208.147

However the BT Speedtester was showing results somewhat higher than these two speed tests, but still very slow.
I raised a ticket and went through all the test procedures to be told...
The results of our tests show no fault with your broadband connection. Completed speed tests show that your connection speed is: none found :?
According to BT, this speed is within the limits of acceptable performance for broadband service. :!:

I have redone speed tests this morning and are more like 'normal' but there is a big difference between BT test results and the other speed tests?
See results..

01/02/07 08:06 2578.45 Kbps 375.84 Kbps 87.113.195.114

Two questions...why the different results, the two other results seem more realistic and could contention reduce my speed from 2500-3000 Kbps to 110 Kbps :?:

Sorry about the long post.
