Hmm . . . about 44% worth of 24 hours.
It has been a while since I last looked at a circuit carrying a G.992.5 (ADSL2+) service.
The SNRM has remained essentially as straight lines. I see 3.1 dB DS and 6.5 dB US. Have you "tweaked" the DS margin to gain an increase in DS synchronisation speed? Assuming the SNRM continues as straight lines throughout the full 24 hour period, then I see nothing particularly wrong with the "tweak". It is advisable to ensure that there is always a minimum of 3 dB SNRM "headroom".
There are a significant number of low level DS CRCs per minute recorded and a few US CRCs. Nothing appears to be outrageously abnormal.
Due to the way the Hlog plot is scaled and presented it shows a staircase effect. The overall bulk shape is as expected.
The QLN plot shows a lot of jitter and, overall, it appears to indicate a wide band of low-level RF noise. The shape is what I describe as "whale-like" (head to the left, blow-hole defined by the dip at the US to DS transition, tail to the right).
Which modem/router are you using? (MDWS has no knowledge and displays "Modem Not Set".)
If you decide to continuously monitor your circuit, you might like to consider using a Raspberry-Pi as a low power means of statistics harvesting.
