I've applied a -30 offset which has given a 3db margin. Gone from 62.7 to 71.6Mb sync. Will have to keep an eye on the ES but they seem similar to a 6db margin at the moment.
Noticed that both downstream and upstream attainable had increased on Tuesday so resynced and got a small increase in sync rate. Downstream attenuation has also dropped from 20 to 19dB, not sure why as nothing has changed as far as I know. Also noticed that FE ES count doesn't seem to reset even after leaving the modem off for a bit.
