Condition index vs confidence

Index 44.0

Condition index (0–100)

Evidence confidence

0.95

Index is an explainable demonstration score, not a probability of failure.

Plain-English explanation

Median wire-to-water efficiency fell from 0.6876 (first week, 7 valid days) to 0.6884 (last week, 7 valid days), a 0% deterioration. Recent median vibration is 6.44 mm/s and bearing temperature 78.75 °C. The cause is not established by these data.

Recent median vibration exceeds synthetic watch threshold
Recent median bearing temperature exceeds synthetic watch threshold
