Well if you pull the strut top in you are shortening the distance between the steering knuckle and the tie rod end. since these are connected the knuckle will be held in place and the strut will turn into the front of the car making your toe go more negative
How much per deg. camber... I have no idea, but I bet it depends just as much or more on your caster angle as well. Low caster=less change.
Experiment and let us know!
