Well at least my vague references don't go unnoticed
DISCLAIMER: I am NOT advocating the download of the entire interwebz
I 'get' the sentiment here about not abusing the network, but with a good few users here voicing their issues with general downloads/speeds, a change of patterns was inevitable as the problems were ironed out.
Paul, Shaun and co are a smart bunch... at least we're led to believe lawyers require some semblance of intelligence (I stay just outside PMB bastid

). As such I think the "allocations" we have been given are a reasonable reflection of what usage could be expected, taking into account the problems experienced by some users.
This was largely the reason for my asking the question of these allocations were calculated. For a 10mb user, I would
say I'm a pretty light user and was concerned I would be unfairly 'punished' for that. Whilst I could still easily surpass the allocation, chances are I won't get close, meaning I'm ultimately a happy camper as things stand.
What I would ask CW, is once the dust has settled and we hopefully remain in this unshaped paradise, what happens when there is a month or two of much-higher-than-normal usage?
