Upstream noise margin, dog slow uploads and erratic downloads

As the only thing that has changed between my last ISP and Plusnet is the login details stored on the router and the ISP it connects to, I was wondering why this has happened, and if it would explain why my uploads (even at off-peak hours) were frequently struggling to get beyond being measured in bytes per second, only sometimes getting into Kbps.
Also, whilst I appreciate that the line is retraining, the download speeds are worryingly inconsistent - frequently varying up and down from low double digit Kbps to 610Kbps+ over the duration of a file transfer (happens regardless of size of file being downloaded, and at peak and off-peak times) where as on my last ISP I was getting pretty consistent speeds nearly always approaching the upper end of what my connection will allow (even during the line training from original activation date)
I realise that may be worrying prematurely (I apologise for wasting anyone's time if I am) and that things may settle down, but the degradation in quality of service between my last ISP and Plusnet has got me twitching that I may have dropped a clanger here.
Current router and line stats:
Bt Wholesale Speedtest:
Current line speed:
7.15 Mb
The profile on the line has dropped from 6 - 5Mbps during the switchover, but I expect it to recover as download sync speed remains similar between Plusnet and my previous ISP
Just for reference, the router stats from my last ISP pre migration completing (I realise that the standard upload speed on Plusnet is only 448kbs so am not expecting it to match my previous isp's 832kbs unless I pay the difference)
Thanks for any help or input to help calm my worried mind

Chris can you put a request to uncap upload to improve this?

I've had a look over your account and can see that you've very recently connected with us. Your line will go through an initial 10 day training period where your line will determine what the best speeds are that your line can cope with, with stability in mind of course.
I can uncap the upload speeds, however as you're on 20CN (Up to 6Mb) you would need to pay for the Max Premium product ( http://www.plus.net/support/broadband/products/prioritised-service-faq.shtml ). When your exchange becomes 21CN enabled (Up to 16Mb) we can uncap your upload free of charge.
Please let us know if you're having any issues after the initial 10 day period. If you'd like Max Premium adding, please give us a shout

Uncapping applies to 21CN exchanges only. He's on 20CN so the only option is Max Premium which costs an extra £7.83 per month.

I've just noticed he's only on 20CN - my mistake

If I get the Max Premium added, is it limited in the amount of times I could add/remove it from my service (subject to notice 30 day period for removal)?
My thinking being that I may add it while I am in the 12 month discount period, but remove it should it not prove to be absolutely necessary once the discount period ends.

You can make this change as often as you'd like, bearing in mind the 30 day notice each time you add it back onto your account again.

Welcome to PN and the forums - sorry to read of your disappointment, however the US SNRM looks about normal!
Who was your previous ISP please?
@Chris / Jelv,
I note with a little concern the OP's reference to US SNRM with their old ISP. Is this possibly a consequence of moving from a LLU supplied service to BT supplied service, even though the 'last mile' is identical - or am I confused? I've seen numerous expectation gaps with migrating users against their old provider, however comparing LLU provisioned service and CN20 / CN21 is like comparing apples and pears - though they are each fruit, they are not the same.
Cheers,
Kevin.

The D-side would be the same, the only difference on LLU is at the exchange. The upload speeds could vary as you say but with a capped upload, there's very little to go off as the speeds are likely to remain the same. I would only really look at the US SNRM if the upload speeds were uncapped and there were problems with the US speed.

My exchange is 20CN and has no LLU.
My last ISP was xilo.net

Doh!!!
For a moment, I'd forgotten that SNRM is inversely proportional to synch rate. In this situation, the higher US SNRM (compared to the previous ISP) implies that the US synch rate is now lower than that provided by the previous ISP.
For whatever reasons on CN20 higher (uncapped) US comes as a chargeable extra. Does anyone know if this is the same with all ISPs due to the being a (chargeable?) BTw bolt-on?

It's not specific to an ISP as it's quite easy to place an order with Max Premium enabled but it would push the monthly price up.
On the whole, most customers wouldn't find the need for Max Premium and would rather pay less for not having it, I imagine.
