Found the timing request via in-game in #modhelp so, here you go!
I found your offset to be off (early) by quite a lot with this as the result -
First timing section:
- BPM: 90.00
- Offset: 208
Second timing section:
- BPM: 180.00
- Offset: 2860
This should result in giving you this for the timing panel
Despite how 'fast' the song actually sounds, it does not go past being 180 BPM flat, it's just a lot of 1/8th spam on the guitarist that the arranger for this song decided to utilise.
After you apply this you will need to change everything to snap onto this timing.
