can anyone tell me what the range/parameters are for the Hub 4 power levels and SNR on 1gig should ~ be?

As far as I'm aware, VM (despite my asking) still haven't come up with this information, nor how to interpret the DOCSIS 3.1 channel data, nor the Hub 4 log entries.
We (forum helpers) mostly assume that the DOCSIS 3.0 channels need power in the range -5 dBmV to +10 dBmV, SNR around 34-40 dB, and upstream power of 34-49 dBmV. But those are assumptions.
