Can you explain (in non-EE terms, preferably) how big of a problem this is in FRC style applications? In my six years of robot building we used potentiometers many times in the feedback loop for rotation, and many more times in our Operator Interface. We never had a problem, and none of my EE mentors ever mentioned it as a potential issue in our many hours of gremlin chasing. Did we dodge a bullet, or is this a case of "it only really matters when you're building spacecraft"? Thanks!
