# Typing Latency Test

> Measure the rhythm between your keystrokes — median gap, steadiness, and longest pause. Different from a words-per-minute test.

## About

Where the typing test measures throughput (words per minute), this test measures rhythm: how many milliseconds pass between one keystroke and the next, how steady that rhythm is, and where your longest hesitations happen. Two typists with the same WPM can have very different keystroke timing — and rhythm is what matters for fast-paced chat, competitive games with text input, and input-latency tuning.

Type a short literary passage; every character-producing keystroke is timestamped locally. When the passage is complete you get the median gap, the average, the standard deviation (steadiness), and the longest pause.

A lower standard deviation matters as much as a lower median: a steady 180 ms rhythm feels far more controlled than an erratic mix of 40 ms bursts and 600 ms stalls, even at the same average.

## How to use

1. **Read the passage** — A short quote appears above the input.
2. **Type it at your natural pace** — Do not rush — this test is about rhythm, not speed.
3. **Get the breakdown** — The analysis runs automatically when the passage is complete.

## Examples

### Reading your numbers

What the stats say about your typing.

Output:

```
Median under 200 ms with a small standard deviation means fluid, confident typing. A long "longest pause" usually marks one hard word, not slow fingers.
```

## FAQ

### How is this different from the typing test?

The typing test scores throughput — words per minute and accuracy. This test scores timing — the milliseconds between keystrokes and how even they are. The two measure different skills and often disagree.

### Do backspaces count?

No. Only character-producing keystrokes are timed, so correcting a mistake does not distort the rhythm analysis.

### What does the standard deviation mean here?

It is how much your keystroke gaps vary around the average. A small value means a metronome-steady rhythm; a large value means bursts and stalls.

### Does my keyboard's input lag affect the score?

Yes — hardware and wireless keyboards add their own latency to every keystroke. Testing the same passage on two keyboards is a fair way to compare them.
