Testing a T1 (Score 1)

There is no way that anyone can guarantee you a full T1 of bandwidth to any site on the internet. At most they can guarantee you a full T1 up to their gateway to the internet. Once you leave the ISP's gateway, depending on what sites you are trying to get to and available bandwidth between the ISP gateway and the site, your actual bandwidth will vary. The internet "speed tests" are designed to give you a ball park figure and not your actual internet connection.
