Declared unit below the precise-location threshold

US state privacy statutes define precise geolocation by a radius of 1,750–1,850 feet — an area of roughly 0.89–1.00 km². A declared targeting unit smaller than that circle (R8 at 0.737 km² does not clear it; R9 clearly not) is inside the statutory precise band regardless of how the unit was produced, so the resolution declaration itself carries a privacy claim, not only a precision claim.

Detection

Declared unit's area below ~1.00 km² (equivalently, equal-area radius under ~564 m) in a jurisdiction with a precise-geolocation statute.

Mitigation

Declare targeting units at R7 or coarser where these statutes apply; keep finer grains internal and analytical
Convert statutory radii carefully — the thresholds are in feet, and a feet/metres slip flatters the available headroom by roughly 3x
Treat any claim that finer units fall outside the statutes as a legal determination requiring counsel, not a spec assertion
