Disclaimer
Understand the device, browser and timing limits behind browser-based scores and measurements.
Browser-based tests are inherently limited by device input, browser timing, window focus, refresh behavior, system load and how consistently the task is repeated. Use the scores as practical comparisons, not as lab-grade measurements, esports certification or medical claims.
Hardware and software differences
Different mice, keyboards, polling settings, browsers, displays and operating systems can change both how a result feels and what number appears. That is why the site repeatedly recommends like-for-like comparisons instead of cross-device bragging screenshots.
Leaderboard and guide limitations
Public score blocks are moderated and filtered, but no public browser leaderboard should be treated as a scientific reference set. Guide pages are meant to explain practical interpretation, not to promise that every visitor will achieve the same result profile.
Comfort and safe practice
Rapid clicking, tapping or long typing sessions can cause strain. Stop if discomfort appears and favor repeatable, controlled practice over forceful bursts. If a technique only works by causing pain or severe tension, it is not a healthy benchmark worth chasing.
