Two ways.
The copper route from my cabinet is easily traced, so I paced it out, (something I learned to do fairly accurately as a teenager rather long ago), added in the cabinet link length, rough height of the pole and drop cable length. Came to a bit over 600 yards.
Then the installation engineer's JDSU showed approximately 0.6km.
My line from the cabinet has always been quite good. The e-side which is now irrelevant for the broadband is poor.
I assume next door's estimate is the same as yours? 53Mbps actual from an 80Mbps sync, if that's the estimate, looks to me as if he has a problem. The IP Profile would be 77.4Mbps, being 24Mbps down from that sounds wrong. What are the "impacted" estimates, and what are the ranges on clean and impacted?
If interleaving has kicked in, that does have a minimum impact of 10Mbps or so with 8ms added to latency. Higher levels of interleaving lose more speed and add more latency. But all that should be covered by the ranges.
