It doesn't have to be "exact" but it has to be explained to a degree. If not, then you could make up whatever shit you want without any real way of knowing how any of it is possible. Fairy Tail has a clear anatomical structure set apart for Mages, the hazards of overexhausting especially for stronger mages the magical storage they possess. Dragon Slayers themselves have the most explanation on their powers and what they can do, even going as far as possessing Dragon traits as a virus that was nullified by the Dragons stored into the particular Slayers (as DUMB as that sounds, that's the bottom line for them)

But the problem is that this is supposed to be the ENDGAME Magic of the Protagonists. We were told what Fairy Law does, the mechanics involved with that and what limitations it possesses. Same thing for Fairy Glitter to a similar extent. All we're given info on Fairy Heart, the Infinite Magic, is that through some offscreen sciency shit that Precht did on Mavis' body while it was cursed CREATED a Limitless Supply of Eternano. Where does the power come from? How does that work? There are so many IMPORTANT questions necessary for this thing to be a valid spell. Even Naruto's most broken Jutsu, Edo Tensei, was given from the ground up all the mechanics, limitations, and scope of power that it entails.

This...this isn't even given a sentence of explanation other than what it DOES rather than HOW it came to be. It shows that Hiro, while capable of writing GOOD material just opted for a lazy route which really pisses me off. I remember the days he wrote well, and had an entertaining show. But now its just lazy garbage appealing to the fanfare that the Fairy Turds are clammoring to. -.-
