ok, this is really only a small problem. I bumped up the animation time to 10 seconds on my system. And i noticed that the meter is not really animated as a real odometer. A real odometer advances the next digit only when the previous digit reaches 9. Your animation "fractionally" advances all digits continously from start number to destination number, all at the same time, which makes it a little bit weird to watch...
