Handtimed

Handtimed refers to a method of timing events, particularly in sports, using a stopwatch or similar device operated manually by an individual. This is in contrast to automatic timing systems, which use electronic sensors or cameras to record times with greater precision. In handtiming, a timer starts the stopwatch when they observe a specific trigger event, such as the firing of a starting pistol or the crossing of a starting line, and stops it when they observe the completion of the event, such as a runner crossing the finish line.

The accuracy of handtiming is dependent on the reaction time and observational skills of the timer. Human reaction time, typically around 0.2 to 0.3 seconds, introduces a degree of inherent error. This means that handtimes are generally considered less precise than automatic times. Consequently, in competitive sports where split-second accuracy is crucial, such as track and field or swimming, automatic timing systems are the standard.

However, handtiming remains in use in various contexts. It can be employed in less formal competitions, training sessions, or situations where setting up an automatic system is impractical or cost-prohibitive. Sometimes, handtimes are used as a backup or supplementary measure to automatic timing. When handtimes are used in official capacities, rules often specify how they should be recorded and interpreted, sometimes involving averaging multiple handtimes or applying specific correction factors to mitigate some of the inherent inaccuracies. The simplicity and low cost of handtiming make it an accessible method for many timing needs.
