Kohi Click Test
Originally from the Minecraft server Kohi, this test measures clicks-per-second over
a longer 15-second window — great for testing sustained clicking endurance.

REFLEX INFO
⚡ What Are Reflexes?
Reflexes are automatic, involuntary responses to stimuli that occur without conscious thought.
They are processed through reflex arcs — neural pathways that bypass the brain and loop directly through
the spinal cord, enabling lightning-fast reactions.
Why they matter: Fast reflexes are critical in sports, driving, gaming, and everyday safety.
A human visual reaction typically ranges from 150ms to 400ms, with trained athletes
and gamers often achieving sub-200ms responses.
📊 Reaction Time Distribution
Average human visual reaction times by category
🧬 Factors Affecting Reaction Time
😴
Sleep
Sleep deprivation slows reaction time by up to 300%. Even losing 2 hours of sleep has measurable impact.
🎮
Practice
Regular reaction-time training can reduce response times by 20–30ms through neural pathway strengthening.
☕
Caffeine
Moderate caffeine intake (100–200mg) temporarily improves reaction speed by stimulating the central nervous system.
🧓
Age
Reaction time peaks around age 24, then gradually slows — adding roughly 1ms per year after age 30.
Even mild dehydration (2% body weight) can slow cognitive processing and reaction speed measurably.
🚀 How to Improve Your Reflexes
Improving reflexes requires both mental sharpening and physical conditioning.
Consistency is the key — even 10 minutes of daily practice compounds significantly over weeks.
01
Daily reaction drills — Use this tool! Practicing reaction tests for 10–15 minutes daily strengthens the neural pathways responsible for fast responses.
02
Racket sports — Tennis, ping-pong, and badminton demand split-second visual-motor coordination, making them elite reflex trainers.
03
Action video games — Contrary to popular belief, fast-paced games (FPS, fighting) have been scientifically shown to improve perceptual decision-making speed.
04
Mindfulness & meditation — Reduces mental noise and improves focus, allowing faster processing of incoming signals.
05
Aerobic exercise — Regular cardio increases blood flow to the brain and has been shown to improve overall cognitive processing speed.
06
Juggling & fine motor drills — Learning to juggle forces the brain to rapidly predict and respond to visual trajectories, building perceptual speed.
