Moving a pot wears out the track, but it also tends to clean the track. Leaving a pot unchanged for a long time seems to lead to a layer of grot appearing everywhere else on the track, which has a similar effect. You cannot win!

I suspect the combined volume and on/off control may have been an attempt to reduce the number of knobs, so that this lovely new piece of furniture they wanted you to buy did not look too much like the control panel at Jodrell Bank.
