I already said further up the threat those estimates are very very pessimistic.
I get 46Mb at the moment and my line is 1022m.
I don't get your point about unreliability either. What is so unreliable about FTTC? I've been synced for 200+ days in the past.
My uptime has without any doubt been 99.9%+
It's understandable you're disappointed that you may now be getting FTTC rather than FTTP but you are underestimating both speed and reliability of FTTC.
Shall I tell you why I am afraid of FTTC? Because it still carries the old copper cabling that will still pose a vulnerability of dropping out!
Here's an example of my current connection.
Broadband Link Downstream Upstream
Connection Speed 14066 kbps 1196 kbps
Line Attenuation 25.5 dB 16.1 dB
Noise Margin 10.9 dB 7.7 dB
When noise margin is above 10dB then my connection is stable for days. The max up time here was 56 days. And that is only when my connection drops out and the router re-syncs at a lower speed such as 14000 kbps. When the router re-syncs at a lower speed and my noise margins go up to 9-10dB then my connection is stable for days onwards.
But as soon as the connection tries to re-sync at a higher speed such as 17000-18000 kbps. Yes I do then get between 15-16 Mbps but my connection instantly drops out within a few days to a few hours and bam noise margins drop to 3.0dB. Guess what happens when my noise margins drop to 3.0dB? Upon heavy rain the connection also will drop-out. I've seen the noise margin as low at 0.9dB when I am lucky that my connection is still on. Sometimes it bounces back to 3.0dB. But most of the times it struggles to handle the higher speeds.
I've been struggling with this issue for years. I've tried connecting hidden test socket, changing filters, routers, called a BT Engineer. Nobody can identify a fault. Even changed ISP's. The engineer in fact said it could be something outside that they'll try to find out what's causing this.
Anyway if the connection drops out and my speed gets lowered and noise margin jumps from 3.0dB to 10dB then my connection is stable again. But even then it will drop out once every 20-50 days or so before connection speed re-syncs back to a higher speed. I don't know if this is DLM (Dynamic Line Management) that's doing this. But clearly it does me no favour to re-sync my speed to something higher when the line cannot cope.
Hence why I was so adamant for FTTP for the benefit of the doubt because then I would feel much, much more reassured that this issue will be solved for good. FTTC might somehow rectify the issue as there would be less copper cabling but still can't be 100% certain. As you may know high-rise buildings are notorious for connection stability. In another apartment of ours where we lived for 4 years and that is low rise there were no drop-outs.
As soon as we returned back to our old high rise building I've had problems with drop-outs. This is the building I've been living here since 1992 and there's always been issues with connection stability. In dial-up days the problem was even worse, drop out every 2 hours. In the past I've also had issues with drop-outs almost every day at least once. In recent time the situation has improved somewhat but the problem still persists from time to time.
