"Somewhere along the line, however, the geometric progression of individual game points was dropped. Instead of the third point scoring 45, it became worth 40. According to the Official Encyclopedia of Tennis, it was most likely dropped to the lower number for the ease of announcing scores out loud, because "forty" could be confused witth any other nmber. In the early 1700s, the court tennis set was extended to six games, obscuring the astronomical origins of the scoring system."
