Terms and disclaimer
Use the drills as a practice reference. Do not treat a browser number as a promise about competitive performance.
Last updated: August 10, 2026
Acceptable use
You may use the public tool for personal practice, education and evaluation of your own setup. Do not use it to misrepresent an official score, to make claims about another person's skill, or to interfere with a game, platform or competitive service.
Measurement limits
Results depend on display refresh, browser scheduling, operating system behavior, pointer hardware, input settings, network-independent local execution and human timing. The tool is not a calibrated input-lag instrument, anti-cheat tool, medical device or official ranking service. Reference bands are a prototype guide and are not population percentiles.
No affiliation

Availability and changes
The prototype may change, pause or remove features as the measurement model is improved. Local history is stored in your browser and may be lost when site data is cleared. We do not promise that a result will be available in every browser or device configuration.
