because the tennis is the most primitive originated in the palace, and would therefore scoring local materials is understandable. They can toggle the clock to get the points, each will get a sub-clock rotation quarter, which is 15 minutes (a quarter, a moment), Similarly, the clock will have two points to 30 points, Of course, all aimed at their convenience basis. This is 15 points, 30 points in the origin.

As for the 40 points, it is more strange, it is not a multiple of 15. This is because in English, 15 min pronounced "fifteen", as the pairs of syllables, while the 30 points pronounced "thirty", is also a two-syllable;, but 45 minutes, English pronounced "forty-five", into three syllables, when the British people feel a little awkward-sounding, does not meet the "convenience" principle, then put it into the same for the two-syllable.

Grand Slam 1-4 disk, if the two sides reach 6:6, it to grab 7, and section 5 is the deciding set, there will not be robbed seven, but to a long drive decisive, that is, one party wins two winning dishes.
