KEYDENZA Flow Score
Speed is loud. Rhythm tells the truth.
Two typists can reach the same WPM with completely different performances. Flow Score looks at the timing between keystrokes to reveal whether the run was steady, hesitant, or driven by bursts.
The space between the letters.
Every valid character keydown creates a timestamp. KEYDENZA compares each timestamp with the one before it, producing a sequence of inter-key intervals. A smooth sequence has lower variation; a jagged sequence has higher variation.
Capture
Character timing is recorded with the browser's high-resolution performance clock.
Clean
Extremely short intervals and pauses longer than two seconds are excluded so accidental doubles and full thinking breaks do not dominate the score.
Compare
KEYDENZA calculates the variation relative to your average interval and converts it to a 0-100 rhythm score.
IKI = current key time - previous key time
variation = standard deviation / mean IKI
Flow Score = clamp(100 - variation x 100)
A minimum sample count is required. The score describes timing consistency during that test; it is not a medical or psychological diagnosis.
A sprint and a groove can finish together.
A typist can produce fast bursts followed by pauses and still average the same WPM as someone who moved at a controlled pace throughout the test. WPM reports output over time. Flow Score reports the smoothness of the timing pattern.
Neither score replaces the other. Speed, accuracy, and rhythm become more useful when read together.
Do not chase a perfect score by typing unnaturally slowly.
The useful question is whether your Flow Score rises while your speed and accuracy remain healthy. Improvement means making your natural pace more controlled, not gaming one number.
Your fingers leave a rhythm behind. See it.
