I think it has something to do with how often you move an element. For example, if you move the object once every second, it will seem choppy. Try decreasing the amount of time between each move as well as decreasing the distance between each move. See http://jsfiddle.net/2K9xP/ for an example.

So we have...

var duration = Math.round(10 * distance);

instead of...

var duration = Math.round(1000 * distance);
