Calculated from 6 data points on October 19, 2026
- What it measures
- Each figure is one row of the dataset: a published measurement for a stated group, traced to its source. The median is the middle value of the 6 figures for this group.
- How it is calculated
- Median of 6 values (4.15, 4.3, 6.59, 6.73, 6.87, 100) = 6.66.
- What it does not show
- Read sentences from Wikipedia in quiet conditions are easier than dictation, conversation or noise. Numbers and spelling variants are not normalized, which counts '25' against 'twenty-five' as an error for every engine alike. One Mac, one run; we make Yap, which uses Parakeet, so we publish everything needed to check us.
