- Its circle scorer separately measures closure, radius consistency, coverage, smoothness, and steadiness before producing one grade.
Field notes
The circle challenge breaks a stroke into closure, radius consistency, coverage, smoothness, and steadiness, then weights those measures into a single grade. Other tests hide or constrain the target: Perfect Timing can conceal its digits, while Perfect Fill hides the line once pouring begins. A Brain Power meter and seven-day streak add light persistence, with both described as device-only data.
