Translate a recent court sprint or conditioning test into an estimated time for another distance. The calculator scales the known performance and then adds separate allowances for turns and fatigue. It is most useful for similar court-running tests, not for converting endurance runs into pure acceleration sprints.
Base time = known time × (target distance ÷ known distance)^1.06. Predicted time = base time × (1 + fatigue %) + 0.18 seconds × extra turns.
Extra turns add time separately because a shuttle is not equivalent to continuous running. Actual turn cost depends on court grip, technique, and line spacing.
The 0.18-second turn allowance is an editable planning assumption embedded in this estimate, not a universal performance standard.
A 100 m court test in 18 seconds scales to 57.7 seconds over 300 m. With eight extra turns and 4% fatigue, the prediction is about 61.4 seconds.
Stopping and reaccelerating costs time that straight-line distance scaling does not capture.
Yes, a modest negative value can represent better target conditions, but values must remain above minus 100 percent.
No. It predicts a timed running course, not skill execution or game impact.
Count turns present in the target course beyond those already included in the known test.
Pacing, turn technique, surface, motivation, and recovery can all change the result.
