Fitness Trend

Explain
Shows speed over time for each heart-rate zone in one graph. Detailed-stream runs use moving samples after minute 8 that fall inside each zone. Summary fallback uses the whole-run average speed only when the whole-run average heart rate falls inside that zone.

Efficiency at HR

Explain
Shows speed per beat of heart rate over time. Higher values usually mean you are moving faster for the same cardiovascular cost. Detailed-stream runs use moving samples after minute 8; fallback uses whole-run average speed divided by whole-run average heart rate.
