Interpreting data
Analytics
What the analytics cards and charts mean, and what to check when values are missing.
Who this is for
Use this when reviewing fitness trends, compliance, recovery, or stale metric cards.
Fitness, fatigue, and form
Metric
Meaning
CTL
Longer-term endurance fitness from endurance TSS only.
ATL
Short-term endurance fatigue from recent endurance TSS.
TSB
Form: CTL minus ATL. Negative means fatigue is currently higher than fitness.
Ramp
Recent TSS/day change. Use it to spot load increases.
Compliance
Planned sessions completed over the recent window.
CrossFit and CTL
CrossFit TSS is deliberately excluded from CTL, ATL, and TSB. CrossFit load is represented through soreness, movement coverage, completed WODs, and planner context.
This keeps endurance fitness from being inflated by strength/metcon work while still letting CrossFit affect planning.
Blank values
- Blank CTL/ATL/TSB usually means no daily_fitness snapshot exists on or before the viewed date.
- Blank recovery metrics can happen when the wearable has not published that field yet, when the cache is stale, or when the wearable needs reconnecting.
- Blank HR zone distribution usually means LTHR is missing or recent activities do not include heart-rate data.
