| with the skill | 0.839 | ± 0.026 | 7 |
| without the skill | 0.757 | ± 0.141 | 7 |
No lift is stated for a state that did not measure one. A spread is the sample standard deviation of the per-case means: a descriptive spread with no coverage probability. The verdict above reads each case's two bands, not these aggregates.
