Cool. That makes a ton of sense now that I think about it. My guitar strings behave just as you described. My brain fart.

Did you guys find that over long periods after the initial stretch it stopped or did it decay at a more constant rate? I only ask because my truck being old needed a front end boost when I got it. It is possible it was adjusted to be where it was but I'm not sure. The bolts didn't look like they had ever been touched.

Also, did you find anything on say a spring that was operated within one range and then much later operated in a more extreme range? Basically I'm fishing for info on our t-bars as we expand the travel windows of our trucks years after they were made.
