Recently the question was how often skaters use a specific skater number so I just had a look at the derbyposition database. While searching for this number Scarollina just asked if we can get the most popular skater numbers out of this database, you can find the answer below ;-)
I think it's a very interesting Question. Whilst derby names are almost unique, how unique are the skater numbers? So if you are curios about how unique your skater number is, just search for it on derbyposition, using a hashtag as prefix like this: "#2808".
