Ugh! After a week of laboriously making an excel spreadsheet, and entering in answers one by one, I finally solve it by mistake while trying a new theory.
Now I've got my dad hooked. He'll be like a dog with a bone, chewing on this for ages. Hahahaha.
Thanks for the great puzzle. Simple and elegant yet fiendishly difficult.
