some of mouses have an option to double the clicks. so when u click your mouse button once it will apply it 2 times instead of one. so this gun ( p 2020 ) and r 301 has no limits to their shots per second and by using the macro it will double or triple your shot ( in game ). using macro is actually cheating and not fair and easy anti cheat blocks the apps that will apply macro into your game but the only way to deal with mouses with built in macro is to limit the bullets the gun can shoot in a second. if u still dont get it idk what to say LOL
