Why the MMP and network disagree: reconcile one install dataset step by step

Synthetic teaching inputs. No real campaign results or industry defaults. Change the values to inspect the model. Calculations run locally; this page sends no data.

Enter network-claimed installs, MMP-claimed installs and the count both systems share after an authorised identifier match. The unmatched network remainder, unmatched MMP remainder and overlap must add back to each source. Do not force a match where the identifiers differ.

Calculated outputs

Assumption sensitivity

Only both varies; all other inputs are held constant. This is not a probability range.

Equations

• Network only: network-both
• MMP only: mmp-both
• Summed claims: network+mmp
• Distinct union: network+mmp-both

Constraints: (both<=network) && (both<=mmp).

Limits

Synthetic teaching data. A real reconciliation needs the same day boundary, app, OS and conversion definition. This does not diagnose fraud.
