That's not "overmapping". If anything its simplifying an otherwise dubious rhythm. Nathan's proposed snapping is more accurate if you want to be perfectly accurate to the song, but that rhythm is really unfitting to the song and section imo. It works, but I think Natsu's current rhythm choice is already very predictable. Not all songs are made for rhythm games, so stuff like this is bound to happen with vocals.
The rhythm currently being used makes logical sense, and the section at 100% speed sounds like 1/4 rhythms. You should anticipate and expect 1/4 rhythm anyways when you consider the rest of the song, the song's pacing and rhythms being employed, as well as the jump spacing, etc...
As well, the instruments are definitely on beat so there is still a consistent and correct offset going through the section.
