## Settlement

Why this grade: Complaints, not animals: one dog can bring several calls, and most strays go unreported. Shown, not settled on.
What it costs to move: Cheap in small numbers. A complaint is a phone call or a web form.
When the source is late: A month prints three days after it ends. If 311 posts nothing for the month, it stays open. A month 311 never posts is void.
Precision: Whole complaints with service code EAE, by created date, Chicago time as the city records it.
