Tune the scoring curves
Play random tasks, then see your raw errors, your scores under the current curves, and the half (the error that scores 50) that would give you a mean of 65 on each task. The target is 60–70 for a typical adult on a Wednesday. Results are kept on this device only.

| Curve | n | Median error | Mean accuracy | Half now | Half for 65 |

Errors: count and area in |ln ratio|, angle in degrees, proportion in percentage points,
midpoint as a fraction of the shape's size, length in ln ratio (0 when right), timing as a fraction of the
target, colour in OKLab distance (0 when right). Curves live in site/js/scoring.js.
