Stress is just how far today's value sits between “norm” (0) and “crisis” (100) — a fixed calibrated scale, not a verdict. It measures pressure, not a prediction of collapse.
This is a year-on-year rate of change, not the absolute level — a level can stay high while its change reads as high stress.
Coal output currently reads -6.1 % YoY, mapping to a stress of 40/100 — modest pressure.
Across the tracked period the stress has eased by 12.6 points.
The value is sourced via official statistics; confidence — medium. How it is derived: Rosstat/CDU-TEK output cross-checked with mirror stats; structural decline.
