On the 15th Feb.2017 I was moved to FTTC.
BTW speedtests over the past week have been very similar to todays...
The upload speeds are especially worrying. Distance to Fibre cabinet is only 500 metres.
So, my question is this, has my Business fibre connection been provisioned at the wrong settings?

From your stats that looks like the best speed you are going to get, I suspect the line length to your cabinet is further than you think, it may not be a direct route. One thing you could check is connecting to the test socket with a filter to see if your internal wiring is decreasing your speed but you are near the top of your estimated speed range so there may not be much scope for improvement.

The line length is correct at 500 metres. From previous engineers visits.
Every thing has been checked see this for previous problems.
So, my question still remains unanswered, has my Business fibre connection been provisioned at the wrong settings?
80/20 or NOT?

very doubtful as my downstream speeds and attenuation are almost identical to yours except my upstream is a lot better but G.INP is enabled on both downstream and upstream

The "Upstream Rate IP profile" from the BTW speedtester being 20 Mbps suggests that it is indeed on 80/20.

It would be nice to have a Staff member screenshot the actual profile in use at the moment. To prove all is well at the Plusnet end of things.

Has @MatthewWheeler not already done that in his post?
Not sure what else you want, seems you are already synching at the top end of your expected speeds, so your set up seems good, seems you are getting as good as you can expect given your distance from the cabinet.

At 500m the OP could in theory get better I'm at that distance and had 65Mb at one point until crosstalk took hold and also being on a crappy Aluminium line doesn't help, I'm currently at 45Mb, i was at 48Mb until i was moved to the new network and lost 3Mb Don't know why that happened and Still haven't been able to get the lost 3Mb back despite re-syncing.
Anyway point being saying that is the best he can get based on the distance to the cab isn't correct.

I'm at somewhere between 800 and 900 from the cab (It seemed to go up when they put me on to a new pair the other Friday).

for what it's worth
this is a snapshot of my connection - line distance to box 453 m
this is after engineer changed out master socket as d/l had dropped to 47mbps ( 80/20 connection)
Actually its now a few mbps better than initial install figures

Estimated Line Length In Metres 897.8
Thank you for the information Anoush.
The distance from my property to the exchange is 2838 metres, as shown here...
Distance from cabinet 42 (fibre) to exchange on g. maps via road is between 2.4km (shortest) and 3.21km (longest)
Distance from cabinet 42 (fibre) to my property on g. maps via road is between 0.48km (shortest) and 0.64km (longest)
Assuming that BT would want the shortest possible length of cable between the exchange and the cabinet, and also add in the fact that at least 4 engineers in the last month have said the line from the cabinet is only about 500 metres in length. I think we can take it that the shortest distances of 2.4km and 0.48km add up near as damn it to your 2838 metre line length. Which makes your estimated line length obselete.
Having a look at the chart here would indicate higher speeds should be available on a "D side" as short as this, with no noise or crosstalk impacting the service according to your testing.
An extra 417 metres added onto any speed estimate would give a much lower line speed estimate, which was proven when I had a problem with the standard broadband, and nobody believing that the line was capable of 7mb because estimates were for half that.
Any ideas where to take this Anoush?

Don't get too fixated on line length. It's not actually the length that matters. It's the resistive characteristics of the line that matters. It's just that most lines in the UK have a fixed and 'standard' resistance per metre which allows line length to be estimated. The figure @Anoush has given will have been obtained via BT diagnostics and calculated by this formula:
<line DB losses>/<standard losses per metre>.
In other words don't take that figure as '897.8 metres long'. Take it instead as 'Losses that would normally occur over a length of 897.8 metres'. It's an important distinction. Your line may just have above average losses at some point - aluminium is a well known culprit that causes that. Another possibility is unusually narrow gauge wire.
As for cabinet location - the original PCP would have been sited to serve the optimum number of properties. Distance from the exchange was unlikely to have been a consideration. No-one has ever much cared about the distance from cabinet to exchange. For sure placement of a cabinet can influence overall cable length but number of cabinets required to cover a given area is more important than amount of copper in the ground. And cable length as regards xDSL performance has probably never been a significant factor for most cabinets.
It is starting to be considered for some in-fill areas (those intended specifically to improve FTTC coverage) but for the vast majority the network designers aren't interested in speed. They are interested in cost.
