Ranking system doesn't work that way. "A" is a rank that signifies the very top, there is no higher base rank than A other than EX, which means "something that cannot be ranked in the usual manner".

Now, a "+" does not indicate the base parameter of the unit, a "+" is used when an ability is capable of being increased beyond the base limit, usually in a short burst manner. "+" is an indication of an ability that can temporarily double the current rank.

For example, Excalibur is A++. That's because Arturia is temporarily capable of at the very minimum tripling the normal capacity of the NP by pouring more mana into the excaliblast. Excalibur has a base ranking that is considered A, which means it is the best possible ranking. However, when it is fully activated, it can exceed it's base power by up to triple that according to how much mana Arturia adds to it.

This is also why Gae Bolg is B. It's not an ability that can be bolstered, it is simply the cause and effect attack. However, it's second form is B+, because it's still considered a B rank attack, but Cu can pour more mana into it in order to achieve at least double what it can do normally.

Hope this helps explain why Cu cannot have "A+" agility, such a thing simply doesn't exist unless he has a predisposed skill or NP that allows him to multiply his usual output.
