Active PGRs are those obtained with games played in the current and previous years.
For example: for the 2024 ranking, the PGR obtained with games played in 2023 and 2024 are taken into account. If the player played for the last time in 2022, the PGR becomes "inactive" and is not considered for the 2024 rankings of PerGioco Masters and PerGioco Rating.
