Masking a blur

Avatar

Level 1

I am making an moving mask of a person walking so I can replace the background (the color key isn't working). Where should I place the mask control points when the image is blurred (showing up as interlace lines) because of movement? In the middle of the blur, or at the 'hard inside0 edge' of the blur, or somewhere else?
