Excellent result
>> Line Attenuation (Up/Down) [dB]: 40.5 / 67.0
What a nice quiet line you must have.. you are doing exceedingly well for its length.
You are currently on the default profile with interleaving set.
TBH I wouldnt touch a damn thing.. thats a sweet result.
Let the Be DLM do its thing, your SNRM may dip a bit tonight.. & need to see how it copes at that speed.
