The 250ms Barrier
The average human visual reaction time is approximately 250 milliseconds.
Pro Gamers (Esports)150-180ms
High Performance180-220ms
Average Human220-270ms
Fatigued / Distracted300ms+
Hardware Bottlenecks
Before blaming your brain, check your gear. "Input Lag" can add 20-50ms to your score.
- Monitor: A 60Hz screen updates every 16.6ms. A 144Hz screen updates every 6.9ms. High refresh rate monitors literally show you the stimulus sooner.
- Mouse: Wireless mice (unless high-end gaming grade) can introduce latency. Wired connections are generally more consistent.
- Browser: Close background tabs. Heavy CPU usage can cause "micro-stutters" in the browser's render loop, delaying the frame where the color changes.

The "Pre-Tension" Technique
Don't rest your finger heavily on the mouse button. Instead, hover it slightly or apply just enough pressure to remove the mechanical "slack" of the button without clicking. This reduces the physical travel distance needed to actuate the switch.
Audio vs. Visual
My Last Second is a visual test. However, auditory reaction time is actually faster (approx 170ms avg). If you play games, react to sound cues (footsteps, shots) rather than waiting to see the enemy.
