Calculating the rating for clans!

It’s easier to handle aging with clans. After all, clan members participate in tournaments across all versions. To what extent – that’s another question. So, aging can simply be applied after each tournament. Also, two tables could be used: a cumulative one that resets each year (results can be stored in an archive or Hall of Fame) and a current one that ages after each tournament. I suggest aging by 10%, as the scores are higher here than in individual play (generally). Although, I haven’t looked into this issue in detail.
