[sdiy] Resolution of analogue potentiometers?

[Michael Zacherl]

Hi, I thought this already has been discussed but couldn't find the thread:
How's the actual resolution of the resistive track of an analogue potentiometer 
specified? On some data sheets I read "< 0.1°" for a rotative pot.

for instance,
in terms of pitch control over a very wide range, using a multiturn pot or trimmer,
where are the limits for the resistive tracks and pots at all?
Technically speaking, leaving practical aspects aside for a moment.

Thanks, Michael.
