| Reference Tension |
The tension a racquet is strung at, or machine tension, which is always higher than Actual Tension. Continuous pull machines (electric, electronic and dropweight) will generally string tighter (5-10%) than a lockout (spring tension) machine, ATBE.

| Resilience |
A commonly used term to describe string responsiveness. Similar to elasticity, a more resilient string is more responsive or lively, providing greater ball speed or power. Specifically, resilience is the speed at which a string (or web of strings in a strung racquet) return to their original position after contacting the ball. Over time, strings lose their resilience, returning less energy to the ball. This loss of resilience causes the strings to play "dead".
