Okay, so I was actually surprised with what seemed to be some really low numbers being associated with high percentiles for various categories, and I think this has to do with all the alts throwing off the numbers. Which makes sense, right? Not only do skill farmers and industrialists tend to have a lot of alts, but I bet all the cyno alts, market alts, mining alts, and all that add up real ■■■■■■■ quick.
Not to mention that there are a torrent of new players trying the game, that don’t stick around for very long. I’m not sure how CCP determined which characters got included in the data set or not, but it’s possible that they included a bunch a characters that were played relatively little.
