Speed Index
Speed index (sometimes speed rating) is a system of rating the performance of Quarter Horse racehorses. The American Quarter Horse Association (or the AQHA) has used two systems over the history of Quarter Horse racing to evaluate racing performances. The original system used a letter grade, starting at D, then C, B, A and the highest AA. Later AAA was tacked on the top, and later still AAAT (for TOP AAA) was made the top speed. Eventually, this system became too cumbersome, and a new system was introduced: the Speed Index system, which used a number system, with 100 being roughly equivalent to the old AAAT. This change occurred in 1969.Close ''Legends'' pp. 6–7 The actual calculation of the speed index starts with taking the three fastest winning times at a particular distance for the past three years at a given track. These times are averaged together, which is then the 100 speed index for that distance at that track. If the average doesn't meet the minimum standard time given ...

American Quarter Horse
The American Quarter Horse, or Quarter Horse, is an American breed of horse that excels at sprinting short distances. Its name is derived from its ability to outrun other horse breeds in races of a quarter mile or less; some have been clocked at speeds up to 44 mph (70.8 km/h). The development of the Quarter Horse traces to the 1600s. The American Quarter Horse is the most popular breed in the United States today, and the American Quarter Horse Association is the largest breed registry in the world, with almost three million living American Quarter Horses registered in 2014. The American Quarter Horse is well known both as a race horse and for its performance in rodeos, horse shows, and as a working ranch horse. The compact body of the American Quarter Horse is well suited for the intricate and quick maneuvers required in reining, cutting, working cow horse, barrel racing, calf roping, and other western riding events, especially those involving live cattle. The Americ ...

Racehorses
Horse racing is an equestrian performance sport, typically involving two or more horses ridden by jockeys (or sometimes driven without riders) over a set distance for competition. It is one of the most ancient of all sports, as its basic premise – to identify which of two or more horses is the fastest over a set course or distance – has been mostly unchanged since at least classical antiquity. Horse races vary widely in format, and many countries have developed their own particular traditions around the sport. Variations include restricting races to particular breeds, running over obstacles, running over different distances, running on different track surfaces, and running in different gaits. In some races, horses are assigned different weights to carry to reflect differences in ability, a process known as handicapping. While horses are sometimes raced purely for sport, a major part of horse racing's interest and economic importance is in the gambling associated with i ...

American Quarter Horse Association
The American Quarter Horse Association (AQHA), based in Amarillo, Texas, is an international organization dedicated to the preservation, improvement and record-keeping of the American Quarter Horse. The association sanctions many competitive events and maintains the official registry. The organization also houses the American Quarter Horse Hall of Fame and Museum and sponsors educational programs. The organization was founded in 1940 in Fort Worth, Texas, and now has nearly 234,627 members, over 32,000 of whom are international. History The American Quarter Horse Association was born at a meeting on March 15, 1940, in Fort Worth, Texas. The original idea had come from articles published by Robert M. Denhardt during the 1930s about the history and characteristics of the quarter horse. In an article entitled "The Quarter Horse, Then and Now" in a 1939 ''Western Horseman'' magazine, Denhardt also suggested that those interested in forming a breed registry meet in Fort Worth to dis ...

Beyer Speed Figure
The Beyer Speed Figure is a system for rating the performance of Thoroughbred racehorses in North America designed in the early 1970s by Andrew Beyer, the syndicated horse racing columnist for The Washington Post. First published in book form in 1975, the Daily Racing Form began incorporating Beyer Speed Figures in a horse's past performances in 1992 and the system now assigns a Beyer number for each horse race. On the Beyer scale, the top stakes horses in the United States and Canada typically earn numbers in the 100s, while extremely strong performances can rate in the 120s. In Europe, Timeform has a similar rating scale that yields a number, but with a different value. The popular rule of thumb for a rough equivalent of the Timeform score is to deduct 12-14 points to achieve the Beyer figure. For American Quarter Horse racing, the Speed index rating system is used. The Beyer Speed Figure is calculated by looking at the final time and distance of the race, adjusted by the track ...

At a time when such data was virtually unheard of, Bull started publishing a racing annual, which evolved into the "Racehorses Of.." series. The company was purchased for a reputed £15 million by the sports betting exchange Betfair in December 2006. Data system According to Timeform, one of its ratings represents "the merit of the horse expressed in pounds and is arrived at by careful examination of its running against other horses using a scale of weigh ...
