Upstream on cable like that will be sub 50 Mbps because they're very intentionally only using a small number of rf channels on the coax for upstream. This is why in my opinion docsis3 is putting lipstick on a pig and is only a short term stop gap solution. The better end state is proper SM fiber to each house.

Yep, even DOCSIS 3.1 modems don't do much for upstream, since generally it remains at 3.0. They have to do physical upgrades, such as amplifier swaps, to actually add more channels and make DOCSIS 3.1 OFDM upstream possible. That seems like years of work, and won't happen any time soon.
