About this Chart
Window is the last 28 UTC days. An active week is an ISO week (Mon–Sun) with at least one card spend. Days per week = spend days ÷ active weeks. First matching bracket wins.
Daily: 3+ active weeks and 6+ spend days per active week. Several days a week: 3+ active weeks and more than 1 spend day per active week. Weekly: 3+ active weeks and at most 1 spend day per active week. Biweekly: exactly 2 active weeks. Monthly: exactly 1 active week. Rarely: first spend 28+ days ago, and no spend in the window. Too new: first spend less than 28 days ago.
Right axis is card spend in the same 28-day window.
