Phone line help

I've been on a mission over the last few days to try and get the fastest internet speed possible and to help me a bit I need a bit of advice regarding BT master sockets. I have spoken to BT and they said providing I do not modify anything before the master socket I can't do any damage.

Here my log of speeds I've been getting...

15th February 2009 - 17.30 - Right before iplate
1525 Down - 511 Up

15th February 2009 18.07 - Directly after iplate
2044 Down 547 Up

15th February 2009 18.12
2042 Down 549 Up

15th February 2009 18.27
2040 Down 548 Up

15th February 2009 19.33
2088 Down 539 Up

15th February 2009 19.47
2041 Down 546 Up

16th February 2009 17.56 - Next day speed dropped
549 Down 536 Up

16th February 2009 22.58
534 Down 524 Up

17th February 2009 10.18
548 Down 535 Up

17th February 2009 12.28 - After router reset
2465 Down 530 Up

17th February 2009 12.28 - After removal of secondary phone sockets
2509 Down 586 Up

The first thing I did was run a speed test showing I was getting around 1.5mb/s, I then installed an iplate which gave me a further 0.5mb/s, I left this for a day or so as inherently it takes a while to fully adjust the internet speed, unfortunately this dropped to 0.5mb/s.. after doing a hard reset on my router this went up to 2.5mb/s... I then this morning did a bit of rewiring of the master socket, bellow...see image..



As you can see there is now only the two blue wires connected but they do not connect to the main part of the master socket at all.. just straight into the face plate and into the router... I disconnected all the secondary sockets.

After this the speed was not really affected just up by about 20KB/s but I was shocked to see it still worked... what exactly does the rest of the master socket do? It's not connected to anything at all and the net and phone work's fine.

Thanks for any incite you can give me.
