if someone maps it it will probably just be mapped as if it was 250bpm or something (1/32 of the original bpm, which is a multiple of 4 and will line up if the song is in 4/4 time)
then they edit the red line to be 8000 bpm.
Camellia could use different divisions and the map would be made differently though.
no song is going to sound good if it was actually that fast, camellia likes do do clickbait like that. only the background noise runs are likely to actually be that fast. actual melody and stuff will be much slower.
(see the 2022 and 2021 new years songs for an example of what I mean)
