The ST should have known better. 20 dB is likely to be the minimum acceptable noise value of the UPSTREAM at the CMTS (Though AFAIK that should be 22 dB according to the DOCSIS 3 spec.).

I have had a contract with cable for 14 years and have just recently renewed, but with BT fibre coming to my area soon this could be the last year.

Here are my latest readings, seem to improved a little later in the day. Do not know if this is due to temperature or utilization? If it is temperature then I expect these figures to degrade throughout the upcoming summer.

As temperature rises, coax expands and offers higher resistance (at its simplest). So downstream power would fall. SNR is not significantly affected by temperature.
So I reckon they've fixed it or a transient went away.
