Your individual play level is adjusted when you play in temporary teams — with smart adjustments based on your certainty level and the sport you play.
In competitions with changing teams — such as Americano formats and open matches — your individual rating is updated. A temporary team level is computed using a weighted average of both players' individual ratings.
After the match results are registered, the individual player levels are updated. Your player level may be adjusted more —or less— than others, depending on your play level reliability. The play level of new players, inactive players, and inconsistent performers are not reliable, so their levels will adjust faster. Regular players with stable performance will adjust slower.
The weight factor depends on the sport. In tennis and padel, the stronger player receives a smaller weight, because opponents typically direct more balls toward the weaker player.
