Steadiness*

Steadiness* is our own metric, not the official app's score.
It measures how much the pressure wobbles relative to its average, over the same samples as Average/Max/Min:
100 − 4 × CV%, where CV% = std. dev. ÷ average × 100.
Rough guide: 90+ very steady (±1 inH₂O at 45) · 75–90 good (±2–3) · 60–75 fair · below 60 unsteady.

* Steadiness is our own metric, not the official app's score: 100 − 4 × coefficient of variation (std. dev. ÷ average, %). Tap the Steadiness box for details.

Conversion

Scale factor Official app: 1.3333 (4/3). inH₂O = raw × 0.1 Pa ÷ 249.089 × factor − zero Zero offset (inH₂O) Official app: 0 (rest reads ≈1.1). “Zero” sets this from the current reading; tap “Zeroed” again (or enter 0) to clear it.
