Other articles, not linked directly here, indicate that there is a lockout on the buzzer if Watson hits it too soon. I've heard anywhere from 300-1000ms delay if you punch in the buzzer before Trebeck stops speaking. I also read that due to buzzer experience, Ken Jennings also advocated to the producers that competitors should be given practice on the buzzer before doing the game. It would make a more fair game. Honorable "battle", if you will.
