Many thanks, every little helps. I appreciate people don't have time to explain it over and over
I've been having a search around and it's tricky finding the search terms that turn up good results, since the various forums out there have "signal to noise ratio" problems of their own!
I have just found mention of R and N elsewhere as well, and calculated ours at 20% as you say. It makes perfect sense as with a "first day or two" speed of ~60mbits it explains why it's reading 47.5 now, the maths add up.
It's far from the end of the world, it's just that when BT's checkers etc say we should get 60-odd it's very frustrating, it's like a dangling carrot. If there's anything I can do to reduce the errors and therefore get the DLM to relent, I'll be a happy bunny. I may resort to wandering around the house with a MW radio set to 800khz looking for noisy PSUs as one person somewhere on the internet came up with. I am seeing a rather high number next to FEC, so unless that drops I can't see it removing it.
PHYR sounds promising if there's any indication they're considering it. I look forward to vectoring as well (not sure, that may be rolling out now?) as that should help curb any "meh, it's just crosstalk" hand-waving.
Pretty much anything that will make the Dynamic Line Nazi chill out a bit is all good.
