, but within the horse racing industry is not referred to as handicap, which is reserved for more general handicapping. WFA is a method of trying to equal out the physical progress which the average thoroughbred racehorse makes as it matures. The thoroughbred matures extremely quickly compared to the human being. By the age of two the horse has achieved 95% of its mature height and weight, and by the end of its third year it will be fully mature. To allow for this variation in maturity in the context of racing, it is necessary to express it as a function of the weight a horse will carry in a race. It is also necessary to take into account the race distance because stamina comes with maturity, and younger horses are at a greater disadvantage the farther they have to run. If no allowance was made, a mature older horse would always beat a younger one.
