I'm going to go out on a limb as a Big Time user and post my previous usage here:

Time Period DL UL TOTAL
Apr 2010 - May 2010 120GB 100GB 230GB
Mar 2010 - Apr 2010 150GB 100GB 250GB
Feb 2010 - Mar 2010 130GB 90GB 230GB

Prior to big time I used about 90GBs a month, of which around 85GBs was DL.

I do quite a bit of analysis on my usage (using personal bandwidth monitoring software) and my extra usage was purely adjusting my behaviour to suit bigtime - the only HTTP Downloads I do is software updates like Firefox, windows updates etc - I have little need for a DL manager.

Most of my extra usage is UL to other NZ users: by line speed I am limited to 400kB/s download and 60kB/s upload (20MB/hour) so most of my usage is on peak to other NZ peers (thus reducing the international bandwidth). [b]Well over 50% of my traffic was shifted to offpeak (2am-9am) and about 90% of my international p2p traffic was shifted from peak to offpeak hours.[/b]

I run a couple of NZ centric websites from my home connection (one is purely for remotely connecting to home) I've found bigtime is excellent for this purpose. I also run folding@home and have found this to use pretty much the same amount of bandwidth as Telecom's smallest data plan.

I am prepared to accept that my usage is higher than most others, but would recognise that it was done in 'faith' of what Big Time wanted.

When I am shifted off Big Time, I will most likely resume my old behaviour, this shifting my offpeak usage onpeak.
