Jackuracy - You can hit the targets when no one is watching, but when so

You can hit the targets when no one is watching, but when someone starts timing you, you miss every shot like you're cursed.

I nailed every shot when no one was looking, but as soon as the clock started, I missed the first target and hit the ground.

I was the best shooter in the group until the timer went off. Then I missed all of them and called it a day.

I hit every target in practice, but when the competition started, I missed the first shot and never recovered.
