The Old Speed/Noise/Loss Issue

I'm on Sky max LLU, 1.5km from exchange ATCF - perhaps 4km by road, I have
about 47db attenuation and SNR anywhere between -1db (!) and 12db. On voice
calls, there is occasional, slight noise, which BT auto tests don't detect.
Sync. speed has been 4864 for several days without problem. I've just done
a soft reboot and speed is 6080, with SNR 7.5db, though no doubt it will
drop off this speed.

I've considered asking BT to send an engineer, but there's a snag. My
incoming line comes via an internal junction box, then an old one-piece rj11
main socket. Recently, I added a filtered faceplate next to the rj11, which
I fed from the junction box because it has screw terminals, and in order to
avoid crimping a mixture of single and multi-strand. I'm confident about my
wiring, but might the BT engineer have a dicky-fit?

Should I expect more, or should I stick while I'm ahead? Are my stats OK?

An SNR below about 6dB is usually not good and causes sync issues.

Any mods you have made by direct wiring to the screw terminals may
result in a hissy fit - it can depend on the engineer - anything can
happen from a bill for the time to 'put it right', the engineer
disconnecting your bits and leaving it at that or the engineer having a
look, tutting and fixing things.
