Well, I think it's hard to get exacts when it comes to networks. What I mean by that:

I never get anything over 25Mbits a second on Cox buy my plan says I get around 100Mbits.

Rapidshare and other websites "limit" free downloaders to around 100KBs sometimes, yet even when they blatantly say the dl limit is 100KB, I can get around 200 to 300.

The N900 tops out at 10Mbits but sometimes I can get 12 or 14Mbits.

Stats like that just goes to show it's never exactly what they say it is.
