1. We have no idea how much effort Blast put into fighting Elder Centipede.

2. The mere fact that he was able to beat Elder Centipede to near death, when the combined might of Bang (a guy who can one shot Dragon Levels) and Bomb (who Murata stated is stronger thasn Bang) was unable to do such a thing means that Blast has to be incredibly powerful. Perhaps not a God Level fighter if we're to assume he put all his effort into fighting the monster, but still very easily a top tier S-Class.
