Start with what was actually recorded
A sleep entry is your estimate of time asleep. An energy check-in is a subjective rating. A wearable measurement comes from a particular device and method. These are different kinds of information, and PeptiBro keeps their source visible.
Compare like with like
Research on wearable heart rate and heart rate variability describes how device methods and measurement conditions affect reliability. Avoid treating different devices or different HRV methods as interchangeable. Consistent context helps make comparisons more meaningful.
Keep the gaps
Your member area displays the number of recorded entries behind an average. Days without an entry remain missing. A week with two check-ins represents those two check-ins, rather than all seven days. The interface makes that distinction visible.
An observation is a starting point
If two things changed around the same time, that does not tell you that one caused the other. Use patterns to ask better questions and reflect on habits. The dashboard is not a diagnosis or a performance score.
