GOSU.AI stats on scoping accuracy
The creators of the GOSU.AI training ground analyzed 100 000 matches in PlayerUnknown's Battlegrounds and found out how accurately players shoot at different distances using different types of sights. The number of bullets fired using each of the existing sights in the game was taken into account.
The x4, x6 sights are the most popular and stable for any weapon at different distances. When shooting at short and medium range: 0-300 meters, accuracy varies from 24% to 36.7%, at long range: 300 meters and more from 15 to 23.6%. The further the distance to the target, the lower the accuracy.
