Ok ok, resolution / accuracy / precision are confusing (or at least
not well known concepts).
Maybe not to us, but in fields like astronomy and mechanical
engineering there are commonly accepted definitions:
Resolution: the smallest difference between two physical values that
results in a different measurement by a given instrument.
Precision: the amount of deviation among measurements of the same
physical value by a single instrument.
Accuracy: the amount of deviation of measurements by a given
instrument from true values.
These are standard definitions in US English that I learned in physics
and statistics decades ago.
