Hi,
The flattening at the ends is the wiper moving over the terminations at each end of the track.
A portion of the ends is used for connection area for the terminals.
If you look you have more than 10K total resistance.
As you have these pots, then do a Proof Of Concept to see if the end effects are going to produce a significant problem.
If you are just using it as a potential divider then actual total value does not have to be exaxctly 10K.
