Frequency across overlapping targets
When two or more targeted geographies overlap (e.g. a store radius nested inside a DMA target), a user in the overlap can receive frequency from both line items, inflating true frequency and reach reporting per user.

Affects
3 conversions
01
Detection
Compute geographic overlap between concurrently active targets; nonzero overlap area with independent frequency caps per line item.
02
Mitigation
01
Apply a global (cross-line-item) frequency cap, not a per-line-item cap, wherever targets can overlap
02
Report deduplicated reach/frequency across the overlapping set, not summed
