The board in the test "used an electroless nickel/immersion gold (ENIG) finish." If you are not using ENIG plating on your PCBs then you may not suffer from the same issue.

The spring tension will definitely cause what you were describing. Take a look at the friction plates between the sprockets. If they get real shiny from wear it can cause them to overshoot when the sprocket advances.
