The phrase when the arrow finds its mark is an old fashioned way of saying a shot has hit exactly where it was aimed, and online it has become shorthand for perfect timing.

Editors pair it with slow motion replays, archery scenes, trick shots and lucky guesses, using the familiar archery image to make the success feel sharper and more deliberate without needing a long explanation.
