Worth getting a profile reset?

[#1]

Rural property, line has been in and working for a couple of months now, seems to be fairly stable (apart from the odd power cut - not Plusnets fault), and me restarting if I have to move things about (decorating, etc).
Anyway, line seems to be profile limited at 4.5 Mbps, but I'd like to squeeze a bit more out of if possible. Looks like I'm limited by my profile. Is it worh getting this reset to get around the 5.2 Mbps area, as per the router sync?
Here's the info;

Unless you can get a little more synch speed, which I doubt, the bRAS won't increase I'm afraid. You're already on a 6db line which won't improve.

OK thanks for the info. Not being an expert on these matters I always value a qualified opinion.
Hopefully the BDUK project will deliver some fibre goodness my way at some point...

F2TC,
You need a bit over 400kbps to get into the next 20CN profile band.
Your stats report a 7.6dB SNRM and the uptime rather suggests a resynch around 23:00 Sunday night.  A resynch during daylight hours might give you enough additional synch to get you up one step to 5Mbps, without causing you instability.  You need to do better than 5696kbps to get up a step and it will take several days for the DLM to process such a small change to the profile.
