That montage needs to be read in conjunction with the other one from the same period.
As still quite a bit goes on using Bearer 0, such as RSCorr etc., now that Interleaving has been applied (at low depths), it might be useful if you could post it (or even better (for me), a zipped copy of your modem_stats.log for say the last 4 days).
See the attached examples from my connection.
Ultimately, I'd like to combine all the relevant individual graphs into a single montage, but I'm still not quite sure exactly what data is worth plotting & what isn't.
EDIT:
BTW, it looks like you haven't updated the graphpd.exe program yet (& maybe also some of the others?).
The current version should be 5.0.0.5
The program updates can be done via the GUI.
