Maximum Transfer on Uncapped ADSL

So Uncapped ADSL is becoming more commonplace and affordable as more and more ISPs craft their own offerings for the public. Now, when one hears 'uncapped ADSL', their are two trains of thought - 1) download as much as you want all day every without having to pay per gig or top up your ADSL account, and 2) just having the convenience of not having to worry about being capped is what it's all about.

Suffice it to say most South African ISPs that offer uncapped ADSL accounts are shaping the service heavily and throttle your download speed to allow for a good browsing experience. For the most part P2P/torrents is heavily throttled, along with HTTP download sites such as Rapidshare, Hotfile etc, which they oddly enough classify as P2P too.

Nonetheless we've slapped together a chart below of roughly what you could expect to download per month were it not for the shaping and throttling.. the chart is slightly pessimistic (or realistic) in that it assumes a maximum achieved transfer speed of 85% of the theoretical maximum speed of the line, i.e. a 4Mbps line's maximum theoretical speed is 4,096,000bps - but due to TCP overheads we use 85% of the line speed as a guideline, which would be ~3,500,000nps (or 440KB/s), as a reasonably accurate estimation of what your line can achieve.

And for our more fortunate brethren in other countries with faster connection speeds:
