Yes, your calculations are correct. Both of these are examples of the children that appear to be randomly chosen and do not reflect the average of their parents at all. I've added this to my list, hoping I can eventually figure out if there's a pattern to these exceptions or if they're truly random.

I also thank you for posting their pictures. I add anything that I can confirm with a picture to my list. I have to actually see the parent and children to be certain the correct numbers are being used. That way I know the exception indeed did happen and it's not just an accidental error of some kind. The more of these exceptions I can find, the more likely I have a chance to figure out what causes them (if they aren't random).

Do you have other children that do fit into the "average of the parents" pattern? I'd like to also confirm that others are getting the same pattern between their parent/child combinations.
