A tool for winning horse race handicapping, it features automatic data input with text and graphical output. It is based on the engineering mathematics contained in the report, \'\'Engineering Analysis of Thoroughbred Racing\'\'. The development of the theory took about a year of research. After that time, the theory fell into a cohesive whole. The reason CompuTrak works so well is because the mathematics is based on engineering principles and provides very useful outputs. Some of them, for example, horse \'\'friction\'\', are unique. CompuTrak 2004 builds upon the proven success of previous versions. Further research now gives you a rating that lets you judge the present Form of a horse, an Improve Number showing you how the capability of the horse has changed from race to race, and the \'\'Magic\'\' Number that combines the Boxer Number and Speed Rating.
