Continuing the story... my 80/20 service went live as expected. Initially at:
Downstream Upstream
Line attenuation (dB): 9.0 0.0
Signal attenuation (dB): Not available on VDSL2
Connection speed (kbps): 71119 19999
SNR margin (dB): 6.2 15.4
Power (dBm): 13.0 -7.2
Interleave depth: 1391 1
INP: 3.00 0
G.INP: Not enabled Not enabled
Vectoring status: 5 (VECT_UNCONFIGURED)
RSCorr/RS (%): 0.0008 0.0350
RSUnCorr/RS (%): 0.0000 0.0000
ES/hour: 0 1.28
Then after 48hrs G.INP kicked in and interleaving dropped:
Downstream Upstream
Line attenuation (dB): 9.1 0.0
Signal attenuation (dB): Not available on VDSL2
Connection speed (kbps): 79999 19999
SNR margin (dB): 6.6 15.7
Power (dBm): 13.1 -7.2
Interleave depth: 8 1
INP: 52.00 0
G.INP: Enabled Not enabled
Vectoring status: 5 (VECT_UNCONFIGURED)
RSCorr/RS (%): 0.0001 0.0375
RSUnCorr/RS (%): 0.0000 0.0000
ES/hour: 0 2.17
It's remained sync'd like that for 12 days but I've noticed that my BRAS profile is pretty poor, given my 79999 sync:
The current Downstream BRAS rate is: 70.61 Mbps
The current Upstream BRAS rate is: 20 Mbps
... by my maths, that's 88.26%
This is all with a stable downstream SnR of 6.5 dB - but with the dreaded ReTx High.

I've now capped the line at 70000 20000 to try to get ReTx low to kick in. I'm a bit fuzzy on why I wouldn't get ReTx set to low anyway, given the >6dB SNR margin and relatively low error rates. Is someone able to explain that please?
Now it's syncing at 70000 20000 the SNRM is nice and high. I'll post the G.INP stats tomorrow as I know j0hn has been tracking them. Fingers crossed that the 70000 cap is low enough - I may not have been heavy-handed enough, so let's see.
