What is the minimum value of the amber zone in the GAR model?

Explanation:
The idea being tested is the time window used to define the amber zone in the GAR risk assessment. Amber represents a developing, moderate risk, so the window needs to be long enough to show a real trend rather than a short-term fluctuation. Six months provides enough data points to smooth out monthly noise and seasonal effects while still allowing timely detection of a worsening condition. Shorter windows, like one or three months, can react to anomalies and produce false amber signals. A full year would delay recognition of rising risk, making amber less useful for early intervention. So, six months is the minimum that balances reliability with timeliness.
