CPS means clicks per second: total clicks divided by seconds. Timing uses performance.now() for accuracy. Warm up your hand, keep your wrist steady, and use a mouse you trust — device and browser latency affect every score.
FAQ
Most people click 5–7 times per second. Above 8 CPS is fast, and sustained scores over 10 CPS are elite butterfly or drag-click territory.
Yes. A responsive mouse with light switches helps. Trackpads are slower, and results vary with device, browser and input latency.
CPS is total clicks divided by the test duration in seconds. Peak CPS is the highest click count inside any rolling one-second window.
Five seconds measures burst speed, ten seconds balances speed and control, and thirty seconds tests stamina — most records are set at 5 seconds.
Normal clicking is harmless, but aggressive jitter or drag clicking wears switches faster. Warm up first and stop if anything hurts.
Both measure clicking speed, but they keep separate records: this page is the 5-second sprint benchmark, while the CPS test page tracks 5, 10 and 30 second runs with peak-burst analysis. Play both — your history stores each best separately.
