a average point is how many points it can be off.
I've already explained why I don't think this is the case in my first response to LaiLai.

Because of this, and also because example two doesn't provide a range of numbers that is less likely on the outside of the range, but MORE likely on the outside of the range, and a range that stretched from .5 away from the average all the way to the same number as one of the parents, I think what LaiLai is trying to do isn't nearly that simple.

No operation like what you describe could possibly, concievably result in example two: something else has to be going on in LaiLai's suggestion.
