@ Roseway & Oranged,
No shooters or any flames !
I'm using the 2Wire 2700HGV diagnostics page rather than Routerstats.
I'd also be surprised if the firmware implementations of bit loading logic didn't vary with at least the modem chipset if not the modem manufacturer as well.
The 2Wire seems to show the same bit loading unless the modem re-syncs, ergo the time of day is not directly concerned.
As it's a lovely dry and cold day in sunny Surrey I thought I'd test the theory by re-booting just for Oranged.
For my pains the modem took 19 attempts between 13:42:38 and 13:46:13 before it managed to synchronise.
The synchronisation rate was down one notch at 192 and the total bits loaded were 79 instead of the previous 92
The three BT speedtests I did this morning were:-
10:32, 76 kbps @ 224 kbps sync speed
13:38, 102 kbps @ 224 kbps sync speed
14:06 97 kbps @ 192 kbps sync speed (after remote re-boot).
Given that these are such atrocious figures I believe we can discount contention and latency problems.
If so, the actual thoughput must be directly related to the real state of each tone, rather than the bit loading or even the synchronisation speed recorded.
Kind regards,
Walter

I think my experiment demonstrates jeffbb's statements.)
