The system is commonly used in track and field as well as athletic performance testing, horse racing, dog racing, bicycle racing, rowing and auto racing. In these fields a photo finish is used. It is also used in competitive swimming, for which the swimmers themselves record a finish time by touching a touchpad at the end of a race. In order to ...
Bracket racing is a form of drag racing that allows for a handicap between predicted elapsed time of the two cars over a standard distance, typically within the three standard distances (1/8 mile, 1,000 foot, or 1/4 mile) of drag racing.
'Rollout' is the distance travelled by a vehicle before the timing lights on a drag strip are triggered. … can affect the final run time by up to 0.3 of a second. … important to discount this first foot of movement from the final run time, to ensure that the run time captured by the GPS data logger is as close as possible to the official ...
To calculate a specific speed index for a specific horse in a specific race, the time the horse finished in is compared to the averaged speed for the distance the race was, and points are added or subtracted based on whether the time was faster or slower than the average.
Race time prediction formula, running course certification. Peter Riegel (January 30, 1935 – May 28, 2018) was an American research engineer who developed a mathematical formula for predicting race times for runners and other athletes given a certain performance at another distance.
The modifications involved circuitry which enhanced the race car's Elapse Time consistency. Vehicle Elapsed Time is a separate, but equally critical, variable to winning a bracket race. The unethical, hidden home brew circuits performed closed loop control of a drag race car's Elapsed Time ( E.T.).
Performance Handicap Racing Fleet (PHRF) is a handicapping system used for yacht racing in North America. It allows dissimilar classes of sailboats to be raced against each other. The aim is to cancel out the inherent advantages and disadvantages of each class of boats, so that results reflect crew skill rather than equipment superiority.
Some races place antennas or timing mats at both the start line and the finish line, which allow the exact net time to be calculated. Awards in a race are generally based on the "gun time" (which ignores any delay at the start) as per IAAF and USA Track and Field rules. However, some races use "net time" for presenting age group awards.
