Line speed dropping

After settling at 50 Mb/s sync my line has started to re-sync and drop in both up and down speeds

 

02:03:24, 08 Aug. ( 131.150000) PPPoE is up -? Down Rate=51300Kbps, Up Rate=19680Kbps; SNR
Margin Down=6.1dB, Up=6.0dB

20:34:02, 18 Sep. (3609097.150000) PPPoE is up -? Down Rate=51065Kbps, Up Rate=18943Kbps;
SNR Margin Down=5.9dB, Up=6.0dB

22:35:54, 28 Oct. ( 129.110000) PPPoE is up -? Down Rate=50490Kbps, Up Rate=19078Kbps; SNR
Margin Down=5.9dB, Up=5.9dB

03:36:46, 13 Nov. (1314155.220000) PPPoE is up -? Down Rate=49872Kbps, Up Rate=19368Kbps;
SNR Margin Down=6.0dB, Up=5.9dB

00:11:26, 21 Dec. (4584969.870000) PPPoE is up -? Down Rate=47372Kbps, Up Rate=17375Kbps;
SNR Margin Down=5.9dB, Up=5.8dB

06:40:32, 29 Dec. (5299501.670000) PPPoE is up -? Down Rate=45760Kbps, Up Rate=17529Kbps;
SNR Margin Down=5.9dB, Up=5.9dB

 

This is now below the line estimate:

Downstream Line Rate(Mbps) Upstream Line Rate(Mbps) Downstream Handback Threshold(Mbps)
VDSL Range A (Clean) 72.5 51.1 20 14.1 44

 

I've had engineer visits before but they always say the speed they measure that day is "what is to be expected for my line length" and just fit a new socket

Re: Line speed dropping

Does anyone have any technical thoughts on this, before I raise a problem ticket?
