Sleep score and recovery: why they differ

A good sleep score and low recovery can show up on the same morning. That is usually not a calculation error: the two displays answer different questions and use different inputs. Before assuming a contradiction, check which factors each display takes into account.

Diagram of three questions: sleep, meaning how long and how deep the night was; recovery, meaning how the night compares to your norm; strain, meaning how much you have done today. Different questions, not interchangeable scales.

Sleep describes part of the picture

A sleep display summarizes the previous night. Which factors it includes depends on the provider: duration, sleep stages, consistency or bedtime. A high sleep score therefore says the night was good by those criteria. It is not a complete statement about how recovered your body is today.

In LeibFit, the sleep ring shows how much of your sleep need the night covered. That need is based on your own nights and rises if you have slept too little over the last few days or had a lot of strain the day before. A nap counts in part.

Recovery adds other signals

LeibFit's recovery score comes from three overnight signals: heart rate variability (HRV) and resting heart rate count 35 percent each, sleep 30 percent. HRV and resting heart rate are compared with your own last 30 days. If your HRV is below your norm or your resting heart rate is above it, recovery can be low even after a long, deep night. A hard session the day before, alcohol, stress or an oncoming infection are common reasons.

There is also a safeguard: if skin temperature or breathing rate is clearly above your norm, or blood oxygen clearly below it, LeibFit caps recovery no matter how good the night was. How the score is put together in detail is explained in How recovery scores work.

Read the difference step by step

First check that both displays are current and that the night's data arrived completely. If a signal is missing, the score is rougher (more in Missing HRV).

Then look at the factors one by one. In LeibFit, "What the value is made of" shows where each signal sits today, for example "below your norm" for HRV or "above your average" for resting heart rate. That tells you which part pulled recovery down. Compare today's combination with your trend instead of setting two numbers or colors against each other.

Use it for the next question

The useful question is not which score is right. It is: what does this mean for today's training? Good sleep with low recovery points towards an easier session rather than a record attempt. On low-recovery days, LeibFit sets a lower strain target for the day. With a training plan (Premium), it also trims your sets on those days. How readiness and strain fit together is explained in Readiness and training load are different. A score is guidance. It does not replace how you feel or a medical assessment.

Frequently asked questions

Should sleep and recovery show the same number?

No. They use different inputs and different scales. Sleep is only one of three building blocks of recovery.

Is low recovery after good sleep a bug?

Usually not. Check the current data and the individual factors before assuming a calculation problem. Often HRV is below your norm or resting heart rate is above it.
