so the first one has a min speed only 20mbit higher, and that is a reasonable guide I think to how my line would operate.
My low clean rate is currently just 62 on vdsl (keep drifting down, presumably with 20th percentile dropping with copper pair degradation and crosstalk issues), that line with a 12mbit higher estimated vdsl speed does not have a impressive g.fast estimate. The estimated upstream rate is actually lower than vdsl, and the estimated downstream rate is not very impressive. This is the issue with g.fast not been able to use both the adsl and vdsl frequencies. Poor tech but cheap to deploy.
