How ClickReflex Measures Reaction Time
ClickReflex is not a game. It is a measurement tool.
This page explains how our reaction time tests work, what we measure, what we don't, and why ClickReflex results are more reliable than generic "click tests".
What Is Reaction Time — Scientifically?
Reaction time (RT) is the elapsed time between a stimulus and a voluntary response. In humans, it consists of multiple stages:
Stimulus Detection
Visual or auditory perception
Neural Processing
Decision making
Motor Command
Signal transmission
Physical Action
Mouse click / tap
Device Latency
Display + input lag
Most online tests only report the final number. ClickReflex separates and explains these layers.
Types of Reaction Time We Measure
1. Simple RT
One stimulus, one response. Example: screen turns green → click.
Useful as baseline, but does NOT reflect real gaming performance.
2. Choice RT
Multiple stimuli, different responses. Requires decision-making under time pressure.
ClickReflex prioritizes Choice RT in advanced modes.
3. Dynamic Target
Moving targets combining reaction speed + motor control.
Popular among esports players for aim training.
Why Most Online Reaction Tests Are Inaccurate
Most browser-based reaction tests suffer from:
| Problem | Impact |
|---|---|
| Low-resolution timers | ±5–10 ms noise |
| Frame-dependent delays | Inconsistent results |
| Input buffering | Hidden latency |
| No hardware awareness | Scores mix brain + device |
This can introduce ±10–30 ms of noise, making results unreliable.
High-Precision Timing in ClickReflex
ClickReflex uses modern browser APIs designed for performance measurement:
This allows sub-millisecond measurement resolution under stable conditions.
We measure consistency, not just speed.
The Role of Hardware Latency
Your reaction time score is influenced by your setup:
| Factor | Impact |
|---|---|
| Monitor refresh rate | 6.9–16.7 ms per frame |
| Input device latency | 1–10 ms |
| OS scheduling | Variable |
| Monitor | Frame Time |
|---|---|
| 60 Hz | 16.7 ms |
| 144 Hz | 6.9 ms |
| 240 Hz | 4.2 ms |
This difference alone can shift your score by more than 10 ms.
Neural Reaction Time Estimation
To help users understand their true response speed, ClickReflex provides a Neural RT Estimate.
// Formula
Neural RT ≈ T_total − (1000 / f) × 1.5Where f = monitor refresh rate (Hz)
⚠️ This is not a medical diagnosis
But a practical approximation that educates users, explains hardware impact, and increases result trustworthiness.
Why Consistency Matters More Than Peak Speed
Two players may both hit 180 ms once. But:
| Player | Average | Std Dev |
|---|---|---|
| Player A | 182 ms | ± 6 ms |
| Player B | 182 ms | ± 22 ms |
Player A is objectively more reliable under pressure.
ClickReflex highlights repeatability, not lucky clicks.

Final Note on Accuracy
"No browser-based test can eliminate all latency."
What matters is consistency, transparency, and methodology.
ClickReflex is designed around those principles.
