I guess you are right perhaps they are now under estimating the speeds. For example I get an estimate of 25mb and get 30mb I am happy however if I get an estimate of 40mb and get 25mb then its endless phone calls complaining about not getting the estimated speed!
Our 'estimate' is down by more than half of what it was 18 months ago. BT finally recognises that, for many, its superfast broadband is a pig-in-a-poke. As with any product or service, a reputable (haha!) supplier should never over-state its potential. That's what BT initially did. Only encouraging complaints and disappointment.
BT's under-estimating of possible FTTC speeds is now widespread across the country.
With estimates being so savagely cut, BT must be well aware that FTTC is gonna get a lot worse in the future, as crosstalk really takes bite.
And with no mitigation available - BT has flumped on vectoring-capable kit that might have helped - nothing in the medium-term can solve it.
The only practical remedy if FTTC isn't going to be ditched altogether - and can't see that happening any time soon - is to rip out and replace all the DSLAMs in the street cabinets for vectoring-capable ones. And turn off all the LLU providers' DSLAMs at the exchange too.
FTTC - an annoying case of like it or lump it. BT had the chance to build a superfast fibre network, future-proofed for a generation to come, but instead it blundered and bought cheap, as usual.
