Do Unused Magazine Springs Wear Out?

"Wear out" may not be the best term...

I know engineers and machinists that tell me springs don't get weak or lose their tension if held static. They only lose tension if they are used through their limits of motion. I know plenty of shooting coaches who advocate changing out magazines once a week to "exercise" the springs and keep them from taking a set.

The two opinions seem at constrast with each other.

Any engineers or other spring experts on this forum (or anyone else, of course) care to comment?

Seems to me if you park a truck and don't move it for a couple of decades, the coil or leaf springs don't "go bad" or collapse. But if you drive it hard, hit bumps, tow a lot, cause the suspension to move, THAT would tend to wear out the springs.
