Why is it advisable to aim an arrow above the Bulls-eye instead of directly at it?

Aiming an arrow above the bull's-eye compensates for factors such as gravity and the arrow's trajectory. When the arrow is released, it will begin to drop due to gravity, and aiming slightly higher allows for this drop, increasing the likelihood of hitting the target accurately. Additionally, environmental conditions like wind can also affect the arrow's path, so adjusting the aim can help mitigate these influences.
