How missing kerosene prices are handled
Kerosene may not be included in every fuel-price event. Salone Fuel Monitor treats each fuel independently, so a blank, null or zero kerosene field means that no confirmed kerosene price was entered for that effective date.
The dedicated kerosene page therefore looks back through the effective-date timeline for the latest confirmed positive kerosene value. Historical charts also avoid plotting a missing kerosene entry as a real zero-price event.
