Pure burst speed
One second leaves no time to tire, so this test measures your top finger speed. The first click starts the clock and counts, so reaction time does not matter. Each click is worth a whole point, so scores jump around: take your best of five.
What is a good 1 second score?
Most people land around 7 to 9 clicks. About 11 is fast, and 16 or more usually takes jitter, butterfly or drag clicking.
