Open the original- What it measures
- The patent lists words per minute, errors per minute and errors per word as performance metrics, computed from the transcript of the sample passage.
- What it does not show
- The patent does not say which adjustment to use. A raw speed and an error-adjusted speed answer different questions, so a test should report both.
