AB  - Tennis has used many different scoring systems throughout its history.  
Researchers have been examining these scoring systems for over forty 
years.  While several intuitive themes have emerged, no systematic 
examination on how different scoring systems affect the stronger 
player’s probability of winning over a range of serving strengths has 
been done. This research study used simulation to examine the three most
 common scoring systems used in the United States and their effect on 
match win probability, total points played, and expected length of the 
match.  Moving from ad to no ad or 10-point scoring can result in a more
 than 3.5% and 5% respective decrease in the probability of the stronger
 player winning a match.  When applied to NCAA Division I team tennis, 
moving from ad to no ad can decrease the stronger team’s probability of 
winning by over 4%.  Changes between scoring systems are more pronounced
 at relatively weaker serving strengths.
