Model changes outside our control
Providers can change a model or API behaviour without notice. Methodology and collector versions are stored, but model identity is not currently complete for every answer.
A score jump may therefore come from the environment. Review it with date, provider logs, and full answers instead of automatically attributing it to brand actions.
Geographic variance
AI answers vary between locations, and a measurement from one location does not perfectly reflect the experience of every user in a country. We define the measurement location explicitly, but it is a sample of the environment, not its complete picture. Results should not be generalised to locations we did not measure.
