Benchmark limits

Direction, not a national fire rate.

The benchmark compares qualifying alerts observed in Lossline-monitored areas during complete UTC weeks. Changing monitored coverage can affect totals as the network expands.

It is not a complete U.S. fire census and does not measure damage, claim severity, owner interest, or closed restoration work.
