WHAT DOES "DURABILITY" ACTUALLY MEAN IN A TENNIS STRING?

Usually people adress the "tear resistance" when they speak of the "durability" of a tennis string. If you are an extreme topspin player or hard hitter, this is logically an important criterion when choosing a string.

Actually for at least 95% of recreational tennis players, durability in the sense of "tear resistance" is completely irrelevant, because their strings break less than once a year and are therefore worn out long before they break. Another aspect of “durability” is therefore much more relevant for them: maintaining the elasticity.
