effective_valuecan differ between requests for the same day
effective_valueis estimated using the other days within the date range you queried — it never looks outside yourstart_date/end_date. This means that querying the same day with a wider or narrower range can return a differenteffective_valuefor that same day, if it changes which neighboring days are available to estimate from.If you need a number for a given day that's stable regardless of the range you query, use
valueinstead, and treat null as "no estimate available" rather than defaulting it to 0 yourself.More info on these rule can be found here.
