How the recommendation works
The tool recommends repair when repair profit is higher than donor profit. It recommends donor parts when donor profit is higher. An exact tie stays neutral so you can test a more conservative case.
Data standard
Direct demo observations and public walkthrough facts are both eligible when their build, source, category, and limits are shown. Four initial demo estimates can seed a planning range, but only a complete job can support an exact-cost claim from purchase through repair or donor outcome.
The low and high estimate bands apply a visible 15% sensitivity buffer around one observation. They are not measured marketplace ranges or predictions of a hidden game formula.
