AFAIK, electrical conduction is dependent on the surface area of the conductor. This is why braided wire works better than solid wire as the surface area of all those little strands vastly increases the conduction. I suspect that if you decrease the area of the jumper-shim very much, the gauge's needle-flutter will return. To me, amp gauges are much like a go-no-go gauge or idiot-light: current is either flowing forward (+) or back (-), so things are working (or not). Exactly how much current is flowing is far less less important than the fact that some is flowing and in the correct direction. But I'm no expert.
