Why an Unbroken String Is Not Always a String That Still Plays Well
Physical life and the time a string keeps your preferred response are different measures.
Player overview
Even without breaking, strings can change in tension, elastic recovery, and surface friction. Each material also has different signs of performance decline.
Measurement guide
- Track time to breakage separately from the hours of satisfying play.
- Mark the session when depth, impact feel, or snapback begins to change.
- Compare value by cost per satisfying hour, not only by the price of one set.
Latest measurement
Durability is the period of predictable performance, not merely the time until the string breaks.
