Some days you need to put up the pistol. Kick back with your favorite beverage and forget about the issue.
The other thing is you need to rewind the shots you made and figure out what you did right. Focusing on the things you did wrong will frustrate you and soon you will start getting worse without improvement.
The top bulls eye shooters maintain a log. They chart each shot and analyse it. When they get in a slump they go back and review the log to help diagnosis what is going on.
It is kind of like driving through a hazard area. If you focus your attention on the hazard you will hit it. If you focus on the path to avoid the hazard you will not be involved in the accident.
