Take your in-platform ROI. Multiply by Recast's incrementality factor. Get the daily incremental ROI you can trust — refreshed every time the model updates.

Platform ROI is the daily in-platform metric your team already sees in Meta, Google, etc. — built from last-click or view-through attribution.
The Incrementality Factor is Recast's adjustment, updated each time the model re-runs (weekly or monthly). A factor below 1 means the platform is over-claiming credit; above 1 means the platform is under-crediting the channel (common for upper-funnel like Linear TV and Podcast).
Daily Incremental ROI = Platform ROI × Incrementality Factor. Once Recast publishes the factor, your team can multiply against in-platform numbers any day. No need to wait for the next model run for a directionally correct read.
