Circle Control: Draw one freehand closed circle with no guide; best-fit radius, radial deviation, closure, coverage, and path efficiency are measured.

Hold and draw one full loop, return near the starting point, then release to submit. The test preserves timing, errors, misses, and control evidence across calibration, pressure, and consistency blocks.
Speed 28% · precision 24% · control 18% · awareness 23% · consistency 7%.
Grades interpret the platform score; they are not fixed global percentiles. A global percentile appears only after the same version, platform, and input mode reach the valid-sample threshold.
Repeat short freehand closed-loop motor control sets with the same device settings. Stabilize accuracy first, then reduce response time without increasing misses.
Refresh rate, browser scheduling, display size, and input latency can affect results. Compare scores within the same platform and input mode.
Mouse / touchpad; selected rhythm and direction stages also support keyboardHold and draw one full loop, return near the starting point, then release to submit. The test preserves timing, errors, misses, and control evidence across calibration, pressure, and consistency blocks.
Visual game-ability test. Rhythm stages support Space, Enter, and directional keys; aiming and control stages require pointer or touch input. Press F for fullscreen.
