Why the Number Changes Every Time You Measure
The contact point used for a light string-bed strike, background noise, and racquet data often vary before the sensor itself does.
Player overview
Frequency-based measurement depends on striking a consistent point on the string bed, controlling ambient noise, and entering the correct string pattern, head size, and gauge.
Measurement guide
- In a quiet room, support the racquet the same way and lightly strike the same point on the string bed each time.
- Recheck the racquet and string inputs, take three readings, and keep the median.
- Compare the trend under matching conditions rather than the absolute number, and note any outliers.
Latest measurement
A good measurement comes from a repeatable procedure, not one supposedly perfect reading.
