I meant to imply that there is no practical limit of the accuracy of
digital gauges while analog gauges are severely limited, comparatively.

Uh... the accuracy of a measurement is independent of the method used to
present the result. An extremely accurate result can be presented using
analog gauges, and can be presented faithfully. (just add verniers and
more hands). An extremely poor result can be presented using digital
gauges, and can be presented in such a way to appear very precise.
