Method
Evidence in, conclusion out, uncertainty stated
Every conclusion traces back to the evidence behind it and the calculation version that produced it.
The five steps
- 1 · Record raw evidence: vehicle details, journeys, energy use, charging sessions, imported vehicle data.
- 2 · Establish the evidence level that this body of evidence honestly supports.
- 3 · Run the versioned calculation for battery condition, range and journey suitability.
- 4 · Express the conclusion as a band with confidence, never as a single precise figure.
- 5 · State what is missing, what remains uncertain and what would raise confidence.
What Mission Check EV will not do+−
- · Call an estimate measured, tested, certified or verified.
- · Publish accuracy percentages, fleet counts or savings figures it cannot evidence.
- · Invent live weather, traffic, elevation or charger availability.
- · Present manual or imported records as independent testing.
- · Give a confident answer where the evidence does not support one.
