Take these figures...

So apparently the tab spaces do not show on some folks browsers, really sorry for the confusion. Looks like this on mine:

Take these figures...

do a basic divide by 53 gives you...

ES: 80848/day
SES: 76/day

That ES rate is not that far off one per second so I think packet loss is a certainty.

I am no expert but assuming the modem is reporting the stats correctly this is not a stable line by any stretch of the imagination. 

The maximum ES/day the line may experience before DLM intervention the following day is around 2880 (1440 in some cases).  Not sure about the rules for SES but from my experience if you get several bursts in a short period of time the DLM usually intervenes immediately.

Your browser is showing the stats incorrectly.
Johnson has provided a screenshot of what he wrote, and it's what I saw.

If others browsers show it different and they want to argue over it that's up to them.

I suspect you have missed out that important three letter word, "not".  ;)

Yes, I've now changed it!  ;D

I'm still of the opinion it is something knocking 5dB off the SNRM.
With a 3dB SNRM it knocks you offline and returns the line to 8dB.

What you could do is leave the line alone when it resyncs at 8dB SNRM with the lower speed and leave DslStats monitoring the line.
It should catch the event happening and show a 5dB drop in SNRM from 8dB to 3dB, then back up again.

Keep a note of the time(s) this happens.

Have you checked if the error bursts coincide with use of the phone or the ringing for an incoming call (even if no handset is connected)?
