Although incorrect in that statement the downloading a few files simultaneously from http://gamefiles.virginmedia.com/ and then adding up the speeds will give you a better figure than Speedtest which can eaily give you greatly inaccurate speeds due to proxies/caches.. BUT you must do all the files at the same time (virgin recommend 4 from two different servers) otherwise you could again fall foul of cached files
