Typing Endurance & Consistency Test
A short typing test captures your fastest comfortable burst. An endurance test asks a different question: can you keep that pace steady after the first minute? Longer sessions reveal rushed starts, uneven rhythm, accuracy loss, and the gradual slowdown that can appear when your hands or attention begin to tire.
Choose a three, five, or ten-minute session. Your overall WPM and accuracy update throughout the test, while KeysInFlow samples your pace every fifteen seconds. At the end, the result compares your opening and closing quarters, reports your fastest and slowest segments, and gives you a consistency score. A higher consistency score means your segment speeds stayed closer to your own average; it is not a comparison with other typists.

How the consistency score works
The test divides your session into fifteen-second segments and calculates a WPM value for each one. Consistency measures how far those segment speeds vary from your session average. A result near 100% means your pace stayed very even; a lower result means you alternated between faster bursts and slower stretches. Because the score is based on your own average, a steady beginner can earn a stronger consistency result than a fast typist who repeatedly speeds up and stalls.
Pace change compares the average WPM in the opening quarter of the test with the average in the closing quarter. A negative number means your closing pace was slower, while a positive number means you finished faster than you started. Use several tests of the same duration and difficulty before treating the number as a pattern. A distraction, an unfamiliar word sequence, or one difficult segment can affect a single attempt.
Build typing endurance safely
Begin with three minutes and aim for an even, accurate rhythm rather than a personal-best burst. If your closing pace repeatedly drops, start the next attempt slightly slower. Move to five or ten minutes only when the shorter duration feels comfortable. Stop if you feel pain or persistent strain; this test measures typing performance and does not diagnose ergonomic or medical problems.
For a short baseline, use the standard typing test. If errors are responsible for an uneven result, run the weak-key analyzer before your next endurance session.
