What rules decide upon the ranking for a chess variant?

You need to have played a (rated) game within the last week, I think, for you to show up in the rankings.

A spot on the leaderboard requires that you have played at least one rated game in that specific variant in the last 7 days. Since you have played your last rated Chess960 game 11 days ago you've automatically disappeared from the ranking.
