First bit of information: Pan American region will receive 42 quotas (38 in 2020).
Three events will allocate quotas: 2022 Pan Am Championships (November) - 1 quota in each of the 12 individual events, 2023 Pan American Games (October 2023), 1 quota in each of the events (2 in trap, skeet and 25 m pistol events) and finally 2024 Pan American Championships (1 quota per event). In 2020 only 2 events served as qualifying tournaments.
The increase in quotas implies that World Cup quotas are decreased? I am not sure...
