Being off by a 16th note even at that speed is – especially for percussive instruments – obvious. The auditory system is especially good at processing serial data, and it has a better timing resolution than the visual one. People with visual-auditory synesthesia are much better at tracking patterns in flashes of light for example (because the hear the flashes).
