Swing arm hydrometers in particular can easily get off target if ever dropped or bumped hard. I trust floating hydrometers slightly more but they also can get off target by deposits weighing them down or fluctuations in temperature.

Refractometers are most accurate and can be adjusted if off target by calibrating.

I agree, hydros can easily be thrown off, even by water temp. I would use distilled water to mark where 0 really is.
