Actually EX can represent the degree of mystery they could replicate, and also conceptual advantage

for example Ea output are generally considered to be about equal with Excalibur at full power, however because Ea have the properties of "space severing wand" it had the upper hand on most weapon of similar power. Avalon does not resist attack bu simply "deny" it by giving any ATK and DMG value the middle finger.. it's EX because rather than creating shield that are tad powerful it creates the concept of "Isolation" instead. Similarly Asterios NP are considered EX because it fully manifest the concept of "Labyrinth,, as in even Asterios can't escape from it and the enemy can't escape from it either unless they have power to destroy space *cough* Ea *cough*  or beating Asterios. there's a reason it had special classification as "Labyrinth" class NP and doing semi-perma interferrence to the world are something beyond mere magecraft and close to the domain of True Magic or Divine spirits.

I dunno bout Kiyo but pretty sure dragon breath are considered powerful enough to destroy a city in a single blow in Nasuverse.. or maybe anything related to dragon are considered EX in here (like Golden Fleece EX that summon clolchis dragon even tho it's considered weak dragon)

personally i'm intepreting "numerical representation is outside our ranking" to be "It's so damn good at what it does, it's useless to compare them with other tool for said purpose",  Both Ark of The Convenant and Shiki MEoDP bring death on contact, however the way of them bringing death are different it's useless to compare them. Gil Sha Nagba Imuru and Merlin Claivoryance or Solomon Revelation function the same way but Gil are so damn unique it's given EX rank in NP, and to be honest it's way better than the other 2 since it's unrelated to external force (Revelation) and it can see not only the present but future, past and even through someone.
