I moved to Infinity (estimate 58Mbps, actual around 70Mbps) and am very happy.
However, I just noticed that BT estimates for ADSL2 on this same line are now 3.5Mbps (between 2.5 and 4.5), and BE estimate is 3.0 (between 1.0 and 4.5).
I'm not too worried as I don't intend to revert to ADSL, but wondered if this is normal, and what the reason is?
Moved (with trepidation) to BT Infinity 2 for upload speed. Happy BE user for several years.
