Why obsessing over one bad night misses the point, and what a rolling weekly average reveals instead.

Almost everyone who tracks anything about their health eventually hits the same trap: one bad data point derails the whole effort. A rough night's sleep, a missed workout, a big dinner out — and suddenly it feels like the day, or the week, is "ruined."
A single night of poor sleep is normal biological noise. Stress, travel, a late meal, an uncomfortable room — plenty of ordinary things disrupt one night without meaning anything about your underlying health. Treating it as a crisis just creates anxiety that makes the next night worse.
What actually matters is the pattern underneath the noise: are you averaging six broken hours a night for three weeks straight, or was last night simply an outlier in an otherwise solid stretch?
THE FAD Score is calculated daily, but the number that matters most is your 7-day rolling average. One rough night nudges it slightly; a genuine pattern of poor sleep, heavy drinking or high stress moves it clearly. That distinction is the entire point of tracking inflammation this way — it rewards consistency, not perfection.
If your daily score spikes but your weekly average stays low, you're doing fine. If your weekly average keeps climbing even on "normal" days, that's the signal worth paying attention to.
