conceivable that the 3.5 seconds includes some overhead related to getting the thing powered up and pointed in the right direction. Also conceivable that it peaked at 50mbps for just a moment. I'll also throw in that whatever protocol they're using...I'm guessing it's not bit torrent over HTTP over TCP :)...has overhead as well to account for errors and OUTER-SPACE related nuances! anyways I'm willing to give them the benefit of the doubt.
