Ratings Earned for finishes in adult tournaments
*Double Elimination Only
A player's rating acts as a lower limit for the tournament divisions that the player is eligible for. For example an A-rated player may play A division tournaments or above (so A, AA, AAA, and Open division tournaments), but not below A division tournaments (B and Unrated tournaments).
Ratings last for the rest of the season earned + one more season. If it is not re-earned, a player's rating will downgrade one level per season. For example, a AAA earned during the 2017 season will last for the rest of 2017 and for 2018. In 2019 it drops to AA, in 2020 to A, in 2021 to B, in 2021 to Unrated.
