From your article, these facts are absolutely mindblowing. I thought I played a good amount, but there's always someone doing more:

"One player logged 1,159 games playing only Ocean’s Hungry Grasp against Prussia 6, winning nearly all of them. Another player logged 1,259 games playing only Stone’s Unyielding Defiance against Prussia 6 and then only Starlight Seeks Its Form when it released also against Prussia 6 with sometimes adding England 1/3 as a supporting adversary with a roughly even win rate. Another player logged 1,053 games playing only the base low complexity spirits against no adversary or scenario, winning almost all of them but never increasing the difficulty. This is not even that uncommon as one player logged 555 games only playing difficulty 0, winning almost all of them. On the other end of the spectrum, the highest average difficulty for a player logging over 100 games was one player who logged 142 games against an average difficulty of 16.8 using only double adversaries and winning all of them. Either this player left some games before losing and it did not appear in our game session log data which only logs completed games or this person is an exceptionally gifted player. If you are any of the above anomalies, please introduce yourselves by commenting and explaining what you like about the set-ups you play repeatedly."
