Requires: No eligible records in this window.
Counted directly from a source record.
An estimator standing in for the thing itself. Always carries a caveat.
Derived from detectable traces only. Reads as a floor, never a share.
Opposite orientation to proxy, so the two never read as one another.
A stated reason and the capability required. Never a zero.
No value, no plotted position, no tooltip, no cell in any download.
| Formula | 108 merged pull requests with a review / 109 merged = 99.1% |
|---|---|
| Sample | n = 109 of population 200 pull requests · 54.5% coverage |
| Excluded | 91 · pull requests not merged (open or closed unmerged) |
| Assumption | Only GitHub review records count. Approval given in a plain comment, over chat, or in person is invisible, so a team with a different review habit will score unfairly low — verify against the listed examples before treating a low number as a finding. |
| Strongest evidence | Rank 1: 54.0 lines merged unreviewed. |
| Repositories collected | 6 |
|---|---|
| Repositories failed | 0 |
| Lines excluded as generated | 555,383 |
| Pull request collection truncated | 6 repository(-ies). Every pull-request metric inherits that ceiling. |
