How to read these Buenos Aires windows

Treat each window as a test, not a rule. Publish inside one window for two weeks, keep everything else the same, and compare reach in Instagram Insights. Because dinner rarely starts before 9pm, so the real, the evening window in Buenos Aires behaves differently from the same clock time in another country — that is the whole point of posting on Buenos Aires time rather than yours.
