We present for your attention a unique statistical review of the World Slalom Series first six years. WSS is a grand project created by World Slalom Skaters Association (WSSA): from 2007 to 2012 there were 347 competitions (426 battles and classics in total) in 32 countries where more than 4500 sportsmen from 55 countries took part. During that period freestyle slalom on inline skates developed into the world acknowledged sport under the wing of FIRS. There were World Championships and all kinds of smaller events in all regions of the planet – Europe, Asia, both Americas, Africa and Australia. We're going to look back at that glorious and difficult time by means of the WSSA Rankings statistical analysis. The best way to learn history is through mathematics.
