Not directly related, and hardly scientific , but the general consensus technique for high level FPS video games is to use arm rather than wrist, with an extremely low sensitivity, as this is more precise and consistent than flicking around with your wrist. It's also generally accepted that people who "aim" with their wrist tend to need to warm up and take breaks more as it is more straining than using the arm. It seems to concur with the conventional wisdom on art, piano and typing.
