Alexa takes the median of all the page load times we observe for a site and then compares that to the same figure for all other sites.
For example, a site in the 98th percentile (Very Fast) has a median load time faster than 98% of all measured sites, while a site in the 2nd percentile (Very Slow) loads more quickly than only 2% of all sites and is slower than 97% of all sites.
