Harvora™ calibration brief
Calibration and reliability at Harvora
Calibration asks whether a probability behaves like the frequency it represents; Harvora keeps sample size, truth source and proxy status beside every published evidence path.
Direct answer
What this supports
There is no single site-wide accuracy figure: frost, water balance, phenology, disease, pests and weather hazards have different targets and evidence tiers.
Intended for Growers, technical reviewers, partners and insurers evaluating prediction risk.
Evidence and method
How the signal is formed
Evaluation keeps metric, denominator, split, truth source and deployment status together; under-sampled or blocked outcomes remain explicitly limited. Qualifying field outcomes enter reviewed calibration and retraining review; submitting an outcome does not automatically update a serving model.
Evidence grade: ESTIMATE
Weather-benchmark measured today; every grower outcome logged in the product feeds the field benchmark it is measured against next.
Boundary
How to read this evidence
The public catalogue does not turn reanalysis, formula reproduction or historical climatology into independent orchard-outcome validation.
