If they've never done something similar of scale and never do the whatever, it's generally hyperbole.
For example, take Negima. One bit... well, it's not so much hyperbole as simple error, but Chamo says Negi in lightning mode moves as fast as a lightning bolt and gives their speed, but as we see it in real action, it's clear that while a lot faster than normal, it's not that fast. Chamo was simply wrong and probably not taking into account that even with lightning form on, Negi has a lot more mass than a real lightning bolt, it's just a partial transformation.
Or One Piece, when Sengoku talked about Whitebeard being able to destroy the world. That's certainly hyperbole, as the quake-quake fruit has never shown more than island busting (and even then, the island it hits was shaken and damaged, not destroyed). At most, he could've been talking about destroying the world in the "World government represents the world," sense, or in the "can go around and destroy all civilization on any island he could reach if so inclined," sense, but the planet as a whole is most definitely safe.

If ^ is the top of a verse full of high-hypersonic and country busting people then its probably true.
If a show has people who are only high-hypersonic and country busting, and someone claims lightspeed and planet busting without doing either, then unless everyone else combined is absolutely nothing to them in a fight, it's false.
Neither hypersonic nor country busting are within 0.1% of lightspeed and planet busting, after all.
