Questions before using this number
Why is this not an exact forecast?
CPI changes with auctions, creative, seasonality, and spend. This is conditional arithmetic using the CPI you enter.
How should I set CPI variation?
Use weekly CPI variation from the latest 4–8 weeks; otherwise treat the default as a planning buffer only.
