The router stats were taken a few minutes before posting, so it is most likely that the changeover occured around 6.00am on Wednesday. As I am away from home now I'll take your advice and over the weekend see if a reboot around midday improves things.
I'll probably stick with the capped upload, as I don't do much for it to be an issue and I would prefer to squeeze as much as I can on downstream speed. The speedtest results may not be rpresentative as I used a wireless connection, I was more interested in what the BT IP profile was in comparison to the PN one (which incidently appears to be unchanging and at 3Mbps).
Other than this I will probably leave things be for a while to see if the stability I was getting on ADSL1 is still apparent on ADSL2. Typically I was remaining in continuous sync for 30 to 60 days, any longer and I would normally aim to manually power down and resync the router. I'm hopeful that my connection could cope with a 3db target snr margin, which could give me an extra 0.5 to 0.7Mbps on d/l speed.

By way of an update, having monitored the downstream noise margin at various times throughout the weekend, it appears that ADSL2 is slightly worse than ADSL1. Whereas prior to the tranfer to ADSL2, the noise margin hovered close to 6dB with only +/- 0.2dB variation, on ADSL2 the noise margin has never been seen to be above 6db and is typically around 5.1 - 5.8. There has been no loss of sync in the past 5 days. The router is reporting a small increase in attenuation (61dB as opposed to 60.5) and 0.0dBm Output power (is this significant?).
There have been reports of recent problems in parts of Cheltenham following some cable vandalism, although I don't live in the areas where problems have been reported so this may not be a contributing factor.
In summary, it does not appear that ADSL2 offers any benefit over ADSL1 in terms of download speed.

Soon after there were some issues affecting the BT network, which caused a re-sync to ~2.8Mbps. The change to ADSL2 gave no improvement over those figures, the biggest increase came from being moved onto 21CN.
