I am around 50-70m from mine.
My stats, has been installed a week today. Have only seen 2 resyncs so far, one was after a few hours so probably the cabinet/DLM testing and the other was me flashing the modem 
Impressed so far, although it will be interesting to see how much of the attainable I lose over the coming months.

Don't know about that, it's the distance from the cabinet to the house I'm interested in.
anyone max rate going down recent? i was first to be in our cab started at max rate of 118m
now the max rate is 89 only a matter of time till its goes below 80...
saying that it was 95 the other down today 89 dunno if thats because i got a profile reset to get my line back to 79999 sync with fast path
how much more will it go down crosstalk effecting it much
first installed 4 months ago
first in the cab

if the max rate goes below 79999 I'm going to set first to the cab lol

Crosstalk is a bitch, my max was 97 and now down to 93, but I have been on my cab for over a year now and it's pretty much full.
When I was moved to profile 17a I was already on a half full cab so never saw over 100mb attainable rate, but I'm sure it would have been at some point
Vectoring is only option to get rid of crosstalk or fibre overlay.
so going by that mine cant really go down much more i hope not..
cheers
btw bt going 30a profile soon?
I can't see it going down much more if any, 17a is only really a 100mbs profile to be fair, I think when you get attainable rates that high even a .5 drop in SNR can knock 10 to 15mb off the max rate.
Sorry that's what I meant, loop length is double the cabinet to house distance. You'd've thought you could get a statistically reliable estimate for this length using aggregate data for VDSL2 connections across the country.
Even broadcom who make the VDSL chipset can't even come up with a formula to determine the correct attenuation, so got no chance at distance
Only a correctly used JDSU can do that.

Ah fair enough then, I thought it might be something people have extracted. Never mind!
For the record I'm about 200m from my cab, syncing at 72/20 with max attainable of 72/28.
