As a tennis expert, I can explain the historical reasoning behind the scoring system that uses 15, 30, and 40. The scoring system is indeed believed to have originated from medieval France. The use of the terms "15," "30," and "40" is thought to be related to the way a clock face was used to keep score. When the hand of a clock moved a quarter of the way around, it represented a score of 15. Moving another quarter to the halfway point signified 30, and three-quarters of the way around the clock face indicated a score of 40. The concept was that if a player reached 45, it was essentially the same as 40, and the next point won would bring the score to 50, which was considered a win, as the first player to 50 with a two-point lead would end the game.
Here's the translation in Chinese:
作为一位网球专家，我可以解释使用15、30和40计分系统的历史原因。计分系统确实被认为是起源于中世纪的法国。使用“15”、“30”和“40”这些术语被认为与当时在场上使用钟面来计分的方式有关。当钟表的指针移动四分之一圈时，代表得分为15。再移动四分之一到达半点的位置表示得分为30，而当指针移动到接近四分之三圈时，得分则为40。如果一个选手得分达到45，实际上与40相同，再赢得下一球得分就会达到50，这被认为是胜利，因为首先达到50并且领先两分的选手将结束比赛。
The origins of the 15, 30, and 40 scores are believed to be medieval French. It is possible that a clock face was used on court, with a quarter move of the hand to indicate a score of 15, 30, and 45. When the hand moved to 60, the game was over.
