Your team's ranking takes into account the average points of its members for the current month (i.e. the sum of the members' points divided by the number of members in that team). The counters are reset on the first day of each month.
The points you earn with your activities push your team up in this ranking! 🆙
Participants who have no activity - and so 0 points - at the moment do not count for the average of their team.
