wiimote IR pointing with mouse

[Capico]

Hi, I've been using the dolphin wiimote new incomplete plugin with dolphin since I use a 360 controller. However, I'm trying to use this plugin to map the IR pointing of the wiimote to my mouse, and I can't figure out how to do it properly. I successfully got the right mouse axis to map to the right directions, but whenever I try it out in a game the pointer tends to "snap" back to the center of the screen very easily and is much too sensitive. I already lowered the sensitivity from 100 to about 20 and that helped a little, but the problem still exists. here is a screenshot of the config: Could anyone explain what the drop down boxes with "center" "width" and "height" mean? they go from 0-100. Is it possible these settings could help?
