Model drift
The gap that opens between a saved model and what the data now says, as the mix of leads and the way they close move on.
Why it matters
A frozen model is what stops the same lead being worth two different amounts on two consecutive days. But frozen forever is a model pricing last year's business.
What goes wrong
Refitting on every upload is the failure in the other direction: a 30-day window one morning and a 90-day window the next produce different multipliers, the same lead is worth two different amounts for no reason anyone can see, and the platform learns from a moving target. The resolution is to fit, freeze, apply, and measure the drift rather than assume it.
What this product does about it
A refit is called for at 20% change, or when any factor enters or leaves the model. Nothing refits itself.

The diagnostic reads a CRM export in your browser and reports your volume, your match rate and the spread between your leads against the thresholds in this glossary. Nothing is uploaded and no account is needed.
