I have started to play cs a little and my ping is annoying me. its around 40 - 50 with maxdsl on Plusnet. I have checked my router and interleaving is on.

My current stats are:

ADSL Link Downstream Upstream
Connection Speed 8128 kbps 448 kbps
Line Attenuation 35 db 9.5 db
Noise Margin 9 db 24 db

I do enjoy downloading at 860kb/s+ with this currently which, im laughing at considering im 5k+ from the exchange. If I ask plusnet to turn interleaving off, what am i expected to get in exchange for a better a ping? Perhas 6 - 7 meg or stay the same at 8 meg :D

I had virtually the same stats as you and I had interleaving turned off. It only reduced my SNR to 8db from 9-10db - my sync stayed the same.
There is no need for you have to have it enabled with those stats.
You're pings should lower by about 20ms.

Are you sure that interleaving's on - your sync rate should be capped at less than 8128kbps if it is (IIRC 7616kbps).
If it is, the flip side is that you might (it's by no means guaranteed) see a higher error rate (which will translate as packet loss) with interleaving disabled.

What's considered too low SNR guys? Mine's 7.0..

The default target SNR margin is 6dB. Above that means you've got some margin for error, below that means you're probably going to a) lose sync and b) get a lower sync rate when you do reconnect.

Yeah, with Interleaving enabled the highest possible sync rate for BT's Max product should be 7616kbps ...

Is this the same as uncorrected blocks? I have thousands... connected at 8128kbps - connection seems pretty stable though?

Uncorrected blocks ~= errors. There's corrected errors as well, that interleaving (among other things) can fix.
