Method and limits
Every indicator is a percentile against the same growing area's own history at the same point in the season, never an absolute threshold. Idaho in October and Wisconsin in February are not comparable on raw volume or raw dollars, and a fixed cut-off would simply re-report the seasonal calendar as though it were news.
Percentiles are ranked against 7 seasons of history. Derived from USDA AMS movement (IF_FV170), shipping-point prices (IF_FV130) and truck rates (FVWTRK). No private order-book data is used.
