I don't have enough knowledge to speak to actual resistance values,
but tencentlife on thesamba.com posted a neat video of an analogue
volt-ohm meter being used to measure consistency of resistance value,
as the flap is moved. I gather that his point was to observe if there
were any drop outs when slowly moving the flap.

The resistive track tends to wear more at commonly used positions.
Idle, cruising speeds.

Image showing what is likely minimal wear on my AFM resistive track:

the arrow points to what is likely around town speeds. You can see
similar wear to LH (highway cruise speeds. Note no wear at LH of
track) and at RH. (idle)
