<P> Although this suggestion might sound attractive, the medieval period ran until the end of the 15th century (i.e. until 1500), at which time clocks recorded only the hours (1 to 12). It wasn't until 1690 that clocks regularly had minute hands when the pendulum system was invented and such a valuable piece of delicate equipment would not have been on an early tennis court where it could easily have been damaged . So the concept of tennis scores originating from the clock face, could not have come from medieval times . </P> <P> Another theory is that the scoring nomenclature came from the French game jeu de paume (a precursor to tennis which initially used the hand instead of a racket). Jeu de paume was very popular before the French revolution, with more than 1,000 courts in Paris alone . The traditional court was 90 ft (pied du roi) in total with 45 ft on each side . When the server scored, he or she moved forward 15 ft . If the server scored again, he or she would move another 15 ft . If the server scored a third time, he or she could only move 10 ft closer . </P> <P> The origin of the use of "love" for zero is also disputed . It is possible that it derives from the French expression for "the egg" (l'œuf) because an egg looks like the number zero . This is similar to the origin of the term "duck" in cricket, supposedly from "duck's egg", referring to a batsman who has been called out without completing a run . One possibility comes from the Dutch expression iets voor lof doen, which means to do something for praise, implying no monetary stakes . Another theory on the origins of the use of "love" comes from the acceptance that, at the start of any match, when scores are at zero, players still have "love for each other". </P> <P> A popular alternative to advantage scoring is "no - advantage" (or "no - ad") scoring, created by James Van Alen in order to shorten match playing time . No - advantage scoring is a scoring method in which the first player to reach four points wins the game . No - ad scoring eliminates the requirement that a player must win by two points . Therefore, if the game is tied at deuce, the next player to win a point wins the game . This method of scoring is used in most World TeamTennis matches . When this style of play is implemented, at deuce, the receiver then chooses from which side of the court he or she desires to return the serve . However, in no - ad mixed doubles play gender always serves to the same gender at game point and during the final point of tiebreaks . </P>
