Max vs. Current sync rates - advice needed
Confusing 
Basically, from memory, if you get assigned a higher SNR, it'll try that for 3 days, then it'll try something lower to see if it's able to maintain a stable service.
It is a bit random though.

All part of the trial then?
I can interpret it easily enough. 
Target SNRM still at 18dB so many fewer bits per tone than "normal".
Other than that nothing is blatantly wrong.

Well..here's an update 3 weeks after posting about these problems... After one of the guys is this thread spotted that my SNR margin was very high (18db), i did a couple of things:
After doing that, i saw the SNR margin drop over a couple of weeks - down to 15, then 9, then 7, down to what it is now (around 5db). Result? Sync speed is up from 4500kps to 7624kps, which gives me an IP profile of 6500kbps - which considering i was getting 1500- 2000kbps pre-ADSL2+, is pretty awesome. It's also around 1000kbps better than that predicted on the Kitz Max Speed Calculator (http://www.kitz.co.uk/adsl/max_speed_calc.php)., given a 47db attenuation.
Once that SNR margin was sorted, things (and maybe i'll regret speaking too soon!) worked pretty much as the experts in this forum describe 21CN should behave. SNR margin was automatically droppped about every 3 days, subsequent resyncs were matched by the IP profile every few days (depending on the % increase in sync speed), and the plusnet profile followed about a day behind. And (touch wood) - things seems stable.
It's taken 2 months, - but i'm finally impressed with 21CN
- Checked the ADSLnation faceplate i'd fitted - and found a slightly loose Blue wire (not ring wire), which i tightened
- Removed a RCD circuit breaker device that was plugged into a mains socket right next to the faceplate.(not sure if this was a root cause of the high SNR or not, though)
