Body Intelligence
One measurement is an anecdote. A trend is evidence.
Any single reading — scale, tape, scan, mirror — is a story about one morning. Stories aren't proof.
The short version
- Every instrument has noise
- Noise cancels. Direction doesn't.
- Consistency is the method
- Judge plans by their slope
Every instrument has noise
Water shifts the scale, breath moves the tape, light changes the mirror, and an estimate carries its label honestly. No single number escapes.
Noise cancels. Direction doesn't.
Repeat the same measurement, same way, week after week, and the randomness averages toward zero. What survives is the slope — the real signal.
Consistency is the method
Same conditions, same protocol, same instrument. A mediocre measure applied consistently beats a perfect one applied whenever you remember.
Judge plans by their slope
Six weeks of consistent points is enough to see direction. That's when a plan has earned a verdict — not on day four, not from one reading.
