As you say, the maths becomes a mess pretty quickly.

Anthony's calculations also have other problems, he assumes that One-College Only Powerstones can be used for Enchanting, which shouldn't work one the item produced belongs to another College and that you don't actually need to use valuables for the Powerstone to work, which kind breaks the name. It also ignores Raise Cone of Power spell.
