Please see attachment. All the readings were taken within a few minutes of each other, and allowing for any stupidity on my part, do not seem to be completely logical. For instance, DSLstats has U/s sync 571 kbps, whilst Speed of Me has 610 kbps, and, moreover, BT has .48 Mbps with profile .83 Mbps.
Any comments for #1 easily confused person? Please!
