Field test
This test is pointer-only — mouse, trackpad or touch — and needs sight of the screen. Everything around the run — starting, restarting, your results — works from the keyboard.
There is no clock — the run ends when the last target does. A miss costs nothing but the time it takes.
The server issues every target position and times the run on its own clock; a run that took less time than the hits it claims, or one averaging faster than any human aim run on record, is flagged and never ranks.
