I think BT has done something very odd with the checker.

Under the 8c profile I was "estimated" at 33.5 down and 8 up.

I have constantly got 40/10 with max obtainable speeds at 50 down and 25 up.

Under 17 a the "estimated" figures are 33.5 down and 14 up.

I still am hitting the 40/10 cap with max obtainable speeds at 92 down and 32 up

I am about 100 meters from the cab and the line checker looks like they are still estimating the same on the downstream and a small increase on the upload.

The trouble is that people may be making purchasing descions on having reliable figures and although BT are showving very conservative numbers it isn't helping anybody when people get hooked up only to find they were way off.

The cost of getting reliable figures per line is probably too high.

The pressure is on to under estimate, after five years of press pressure over the ADSL estimates that were generally over generous for many people.

Maybe everyone is correct.

The checkers are so variable, that without precise inside information it is hard to say anything for sure.

Well my actual rates are better than estimated and the BT guy said I could get 140/30 max so I'm gonna get 80Mb without a doubt as I'm maxing it out at 40Mb.

My current estimate is exactly 40Mb.

Our test also indicates that your line currently supports a fibre technology with an estimated WBC FTTC Broadband where consumers have received downstream line speed of 40Mbps and upstream line speed of 10.9Mbps.

Not so. My estimate is 30, I sync at max and get 36-37 throughput (39 on the BT Beta test).

The last technician visit showed hi 60s and my modem indicates around 66 so I would hope that the checker will rise. Having checked my number and that of several neighbours - all closer than me including one with a line length of around 50m, they are all showing 30.5 down but upstream from 12.1 and up as the line gets shorter.

There are differences between the BT Residential and BT Business checkers. The Res' gives an upstream max of 10Mbps for the lines around here whereas Bus' gives 12.1 and I did find one with a downstream differences too

Currently getting 33Mb down and 5.5Mb up

Our test also indicates that your line currently supports a fibre technology with an estimated WBC FTTC Broadband where consumers have received downstream line speed of 40Mbps and upstream line speed of 14.6Mbps.

My d-side cable length is 89m. I'm expecting to get the full 80. I'll let you know soon as I'm due to go on the trial in the next couple of weeks

Interestingly, i also get a full 40Mb estimate, yet I won't see anything near 80. Maximum attainable is currently sitting at around 59.

Edit: actually its probably just my 17a estimate capped to 40Mb.
