no, not unless you're trying to move pixel by pixel. at normal mousing speed it should record a stable polling rate otherwise there could be something wrong. here are my results from the mouserate checker application at normal desktop mousing speed. only when i tried to push my mouse as slow as i possibly could did it show different numbers. it was the same at 750hz too, perfectly stable at normal mousing speeds.

compare this to goldenfrag's image here - http://www.techenclave.com/forums/bad-63860.html
i wonder at what speed he was trying to move his mouse though.
