Exceeds chance
This overlap count exceeds what would typically occur under random shift assignment (beyond the 99th percentile). This does not indicate guilt—it indicates that roster-based analysis alone cannot rule out chance, and professional statistical review by a qualified expert (e.g., Royal Statistical Society accredited) is strongly recommended before drawing any conclusions.
Warrants review
This overlap count is elevated but not extreme. It may warrant internal review to understand rostering patterns, but does not by itself indicate wrongdoing. Consider consulting with departmental leadership.
Within expectation
The observed overlap count falls within the range expected under random shift assignment. No statistical anomaly is indicated.
Exact percentile and tail-probability readout will appear when the manifold pack includes the simulated max-overlap distribution.
