I meant I think its unlikely BT will market higher than 100mbit just on vectoring alone.

If they did rollout 120 with profile 30 and vectoring or just vectoring/profile 30 alone I guess it makes you happy but I dont see the point, BT already win on headline speeds with FTTP and FTTPoD (which soon will be available in all FTTC areas), and most FTTC consumers are on 40/10 or 40/2.

Regarding my 110, sadly I didnt create any graphs, I unlocked the modem, the first night in the gui it showed 110, which dropped to 105 in the evening.
The next day it was at 90, which I then did make graphs, those graphs showed some QLN but it was low.

Now is some confusion, apparently when I got enabled a bunch of adsl lines got knocked offline, I suspect they forgot to enable the adsl power cutback when I was enabled (I was enabled before exchange was officially enabled), so its possible the 90 to 110 difference was due to full power on the adsl tones.

When the line dropped from 90 to 73 there is a clear QLN increase across pretty much all the vdsl frequency with most of it on the first downstream range. So my guestimate is crosstalk at least for the 90 to 73, but not so sure for the 110 down to 90. My install engineer did link both times to new installs tho so he thinks its crosstalk for both.
