if your concern is about the right click / left click :
did the player play sniper ?
is there a quick scope in the game ?
does the accuracy change when scoped ?
depending the mouse it could be a “fat finger” issue where the player press both keys at same time , but usually you have the inverted sequence
anyway the session is 9 minutes , it’s too short to state , come back with a longer one and I will be able to be more precise
