Bell Curve GraphThe Hardware Factor: Input Lag & Latency
When benchmarking cognitive speed online, the device you use can add significant delay. Standard browsers, monitor refresh rates, and input devices add "hardware latency" that artificially inflates your visual response score.
| Hardware Setup | Estimated Input Delay | Impact on Score |
|---|---|---|
| High-Refresh Gaming Setup (240Hz+ / Wired Mouse) | 2 - 5 ms | Optimal / No impact |
| Standard Desktop (60Hz / Wired Mouse) | 10 - 20 ms | Adds ~15ms delay |
| Office Wireless Setup (Bluetooth Mouse) | 20 - 45 ms | Adds ~30ms delay |
| Mobile Touchscreen (Wired / 60Hz screen) | 50 - 90 ms | Adds ~70ms delay |
| Mobile Touchscreen (Wireless / Bluetooth lag) | 100 - 150 ms | Adds ~120ms delay |
Screen Refresh Rate: A standard 60Hz monitor displays a new frame every 16.7ms. A 240Hz gaming screen refreshes every 4.1ms, allowing you to see the color change up to 12ms faster.
Mouse Polling Rate: Wireless office mice often poll coordinates at 125Hz (every 8ms). High-performance gaming mice poll at 1000Hz to 8000Hz, reducing input processing delay to sub-millisecond ranges.
Mobile Digitizers: Smart devices queue touch coordinates before sending them to the browser's JavaScript event loop, which introduces substantial input latency. For clean visual reflex scores, desktop low-latency configurations are highly recommended.
