That sounds like a slight miscalibration of the eye tracker. Assuming perfect eye control, if the tracker estimates your gaze slightly incorrectly then the cursor will always move away when you try to look at it.

No such thing. The eye does constant micro movements and the brain filters this out. You can compensate for this in software but it lowers the target accuracy.
