This is one of the best videos about how these work. I would think the springs would being worn have more an affect than the magnets. Your should try getting a estimate on number of revolutions per mile. jack it up . roll the tire and see how many times that cable turns. A little math or online calculators can tell you how many spins the cable is doing and is it at where its supposed to be. The fact that it is even across the range seems to be more of a ratio being off gear or otherwise and that should be easy to get closer. finding the right gear of course.

What makes it work...
