Yuk indeed.

Here's statistics for the latest 7 days: http://i.imgur.com/IjTXF.png

I'm still concerned with the RSCorr graph, but I'm not sure if I can justify calling BT or whether they can ever do anything about this if it's some appliance outside of the boundaries of my house which is causing interference.

Just a comment:-

When plotting the graphs, it helps to use multiples of 4 to keep the time along the x axis in order & easier to detect patterns, especially when plotting a few days together.
e.g. 40 m, 8 d, 12 h etc.

I see. I'll do that next time I submit one.

The good news is DLM has restored my previous profile of 73322 a slightly lower interleaving depth again. I was disconnected early this morning, but not by lack of noise margin or massive errors, so I can only presume DLM did this. It happened around 5am from what I can see.
