I'm not a big fan of how they calculate load time. Usually you'll start interacting with the website before every single external resource loads (comments, Facebook integration, tracking scripts, etc.). Also, they should be comparing against Chrome/Safari with adblockers. Comparing the load times of one browser blocking the majority of the data downloaded vs one browser downloading everything will be very different regardless of what you're using.
