A fast shooting squad should be avoided. If you can't avoid it, then make sure you maintain your own internal and external timing. This will reset your setup timing to remain consistent. A slow and sloppy squad's timing can be managed only when you are aware of the problem. Watching a shoot off you will see good shooters miss targets due to unfamiliar squad timing altering the shooter's normal set up and timing.
Awareness is concentration. .
Do not focus or mentally respond negatively to distractions. Gun jams, misfires, background noise is all part and parcel to the game. The moment you allow yourself to be distracted your score will suffer. Learn to block out distractions by listening and observing them, then they will no longer be distractions, just normal sounds and events. . Pay attention of where the shooters on your squad are breaking the targets.
