hope this is what you require
I'm around 800-900m from cab don't know exact but line follows the road
Everything looks quite good then for that distance.
Some users are half that distance, but achieving poorer speeds than your connection.
line was fitted around 25 years ago
Internal line is around 60ft long from dropwire in loft to master socket no extensions although internal cable has 3 joins in it (jelly crimps) as various engineers wouldn't put a new cable stating they where not allowed to do lofts anymore.
There are no visible 'problems' in your Hlog & QLN graphs.
It's worth monitoring the stats over a long period, to see how things go.
You now have a set of base data to compare against.
If you are connected to a newish cabinet, with few other users, it's likely that your sync speeds will reduce in time as more users are connected, increasing the effects of crosstalk.
Over a 12 month period, my 1050m connection took a hit (in small visible stages) of around 10 Mbps on DS sync speed (from 30 Mbps to 20 Mbps).
My cabinet is now almost full (according to an engineer who visited to investigate my speed loss), so things shouldn't really worsen for me.
My connection has recently gone back to fastpath (from ain Interleaved depth of around 350) & I have seen a slight increase in sync speeds.
Maybe one or two users have gone back to ADSL or have discontinued their connections.
BTOR are currently trialling Vectoring, technology to reduce the effects of crosstalk.
If/when it gets rolled out, I & other users may see some improvement in sync speeds.
