As spudgun suggested, I am reposting my stats.
As far as I can see, nothing much has changed and my download (not sync) speeds seem to have settled at around 23 Mbps. This is much lower than the advertised average of 36 Mbps and slower than the 30 - 37 Mbps that I was getting for around 5 weeks in mid summer. However, it is just a little above the minimum guaranteed speed set by the ISP.
