Sadly your stats don't make any sense at all.
Actually yes they do, I thought they looked familiar. What are you trying to pull pretending you are on 50M with a 10M upstream?
You took the service flow information from
http://www.cableforum.co.uk/board/34915791-post39.html
The modem log copy/paste is not from a 50M modem.
The downstream information copy/paste is not from a 50M modem.
The upstream information copy/paste is not from a 50M modem.
The downstream frequency is incorrect for 50M - this channel has 38Mbps of capacity available so your 'speed test' is impossible.
The upstream frequency is incorrect for 50M.
The upstream symbol rate is incorrect and expressed in incorrect units, this is I think a bug with one of the SA modems.
