For example, in CS: GO, even without macros, in order to increase your efficiency and raise your K / D ratio, in some situations it is more efficient to stop your spray for a split second and start over (or just aim to give one exact “headshot”).
So with macros, in order to reduce the influence of recoil factors, after 15-25 shots, it is better to stop the spray and continue it after a pause, aiming again.
It should be understood that if you lack a clip with a macro of 20+ shots for one target, it is either not the correct shooting distance, or low aiming accuracy (usually due to the high sensitivity of the mouse).
