Counts are profile-wide, point-in-time research labels. They never affect the insider score or ranking.
Every completed outcome is shown; n<5 is descriptive small-sample evidence and is not scored. Disclosure-level observations published on the same date may share a return path and may not be statistically independent. These results never affect the insider score or ranking.
