When mechanical-electric timing is used, the climbing time is displayed with an accuracy of one-hundredth of a second. In the rules modifications in 2018, the possibility to use manual timing was removed, and the mechanical-electric timing should record with a precision of 1/1000 second. This precision is only used for ranking in case of a tie.
One barn is equal to 1.0 × 10 −28 m 2. The name derives from the folk expressions "As big as a barn," and "Couldn't hit the broad side of a barn", used by particle accelerator physicists to refer to the probability of achieving a collision between particles. For nuclear purposes, 1.0 × 10 −28 m 2 is actually rather large. [25]
[25] [26] The standard FIFA football pitch for international matches is 105 m (344 ft) long by 68 m (223 ft) wide (7,140 m 2 or 0.714 ha or 1.76 acres); FIFA allows for a variance of up to 5 m (16.4 ft) in length in either direction and 7 m (23.0 ft) more or 4 m (13.1 ft) less in width (and larger departures if the pitch is not used for ...

In terms of judging a person's speed, the best method of timing is through lasers which start and stop the times when passed through. A laser start (from a stationary position) is more accurate for measuring pure speed as it does not register a runner's reaction time, however, this method of timing a 40-yard dash can affect the accuracy by as much as 0.5 seconds with the manual stopwatch method.
The advanced "Level 3" version introduces a 15-second move timer mechanic. Use of the 15-second timer is optional; it does not have to be used. Either player may use the 15-second timer during their opponent's move to force the opponent to complete their move or face a penalty. The 15-second timer can only be turned over when the upper chamber ...
