gumshoe2029, i think i many not be using your capx correctly; because the zoom effect is not smooth and the jump from location to location seems with too big of a gap.
You can adjust the amount that it zooms by. Simply adjust the parameter, "zoomSpeed" to see what I am talking about. If you want a smoother zoom, try a zoomSpeed of 0.05 or 0.01.
Unless you are referring to the mouse pan. You can adjust the equation for that too to be smoother. On our live game client, I use a differential averaging process to smooth out the pan when you are zooming. You also need to make sure that your layout is sufficiently large and that you have unbounded scrolling set to yes, otherwise it will jump like my example does. If you set the layout size in my zoomTester to 10000,10000 then it will zoom more smoothly too.
Our zoom and pan is below:
