Are hand times slower or faster?
In general, hand times tend to be faster than those obtained via FAT. This is because a human timer must react to the starter’s gun (creating a small delay in starting the clock), and also because human timers tend to anticipate the athlete’s crossing the finish line, and tend to stop the clock slightly early.

When did electronic timing start?
