Checked against its source on October 17, 2026
- What it measures
- Both rates come from the same participant and the same copy task.
- How it is calculated
- 49.7 / 30.6 = 1.62, so 62 percent faster
- What it does not show
- The faster condition was less accurate (96.5 percent against above 99 percent), so speed and accuracy traded off.
