Field notes
Each test gives instructions before play, then accepts a typed estimate, a tap, or a drag-and-release depending on the challenge. Scoring uses a smooth curve: the page says half the points remain at a test-specific error distance, while half that distance earns 84 points and twice that distance earns 6. The final result also assigns an S-to-F grade.
