Tips for an accurate result
If a result seems unusual, re-enter your inputs carefully before assuming something is medically wrong — a typo is far more common than an anomaly.
Use the same units consistently (all metric or all imperial) — mixing unit systems mid-entry is a frequent source of errors.
Keep a simple log of results over time; a single app or notebook is more useful than remembering numbers from memory.
Treat any single result as one data point — trends over weeks matter far more than one reading.
