speeds are faster but SNR Margins are halved so it may be a short term speedup until the next retrain !
You may be right. How long it will remain at 3dB for is anyones guess. Looking at your graphs daily variance looks to be around 1.5dB, so it may hang in there but experience lots of errors. atm it certainly doesnt look like you'd get that speed again now if you rebooted.
Your DS FECs have certainly increased.
Id keep an eye on the DS Err Seconds though, because if they continue to be high then the DLM is going to cut in anyhow. How many over the past 24hrs I cant tell from the graph
If so, Im wondering if you perhaps just call it quits, and realise that the DLM
is likely to notice - In fact it looks like its already done so - Ive just noticed the increased interleaving depth.

As regards to the graphs, not seen anything like that before. Are your dailies like that, or just the 3 day run
From the missing blocks in the interleaving and uptime, it doesnt look like its been recording all data.
