Interesting that in the hoo-hah I'd completely lost the fact you were on ADSL2+ until XRaySpeX pointed it out.
Re a question in your opening post -
"so after 10 days or so I ask for a lower snr profile". Nope.
The 10 days is a period when the BT Wholesale system merely notes your lowest connection speed and sets that as the Maximum Stable Rate. From that it calculates the Fault Threshold Rate, either 70% or 80% of the MSR.
The value doesn't really matter any more. The FTR used to be the figure above which you would have a heck of a job getting a sync speed problem reported by your ISP to BT Wholesale, as the reply from BTW would be that it was still within range.
Now it seems to be ignored and if you have a connection that works at all then you can have a fight on your hands getting it looked into properly. It probably started soon after Openreach started charging over £100 for "No fault found", even when there evidently is one - just they couldn't find it.
The SNRM is determined by the DLM and runs from the first connection forever. As far as I know you can't ask for it to be set to 3dB like you could on O2, but some time last year the DLM was modified, and given a sufficiently stable line it drops it to 3dB automatically after a several days. Whether it won't do that until after the first 10 days I don't know - that would seem logical.
