Would that really even be breaking the record? Usain Bolt could easily be beaten in a race by, say, a car. A cannon would win the olympic shot put contest handily. The record is "who is the best human at X," not "what is the best X."
Reminds me of bowling robots, although in the case of bowling, being too consistent is a problem because it wears away the oil, impacting the path of the ball.
